Experienced riders to teach your high-speed driving rain, the right way – Audi, highway, car owners
Article by jekky
The highway from the rain Car Tail splashes, it is obvious to see that car tail gas flow lines, which can show the vehicle driving stability and grip, at least you can see the bottom of the vehicle air guiding system is perfect or not, and the rear wheel positioning degree of precision. Some car is messed up a large spray, and some cars are a big group rotation mist. I read an A4 tail splash of water mist, is equal in diameter, the same height (about 1 meter high), two groups mist, on the left of a group is rotating clockwise, the right is a group of rotating counterclockwise, that they are symmetrical, it is neat, then that car more than I Yiqijuechen away, leaving only two rows of symmetrical rotation of mist, my feeling is that good spectacular, beautiful and powerful imagery of! A4 driving ability in the rain, hey, it goes without saying we all know now?
Also have seen an attempt to drive the Audi crossed the water zone in the performance, saw his throttle, suddenly rushed into the water area of Audi cars, but unfortunately, no seconds, no car moved, then he had to find someone to pull the car out. Said next, a look he is a novice, do not know how to push through water district.
So, no matter how good car, we can not correctly grasp the number of rainy days, driving the right way, may put themselves in danger, as with me to see that those principles must be observed it driving rain.
Old drivers know to drive applications running in the low water zone block, and as far as possible do not stop, do not shift, to make full use of local deep water driven out of inertia. If the engine stalling in the water, can not be used methods such as carts and forced to fight motor start, should find ways quickly pulled from the water out of the car, unloaded Spark Plug, Start the engine in the water from the engine. If the water depth more than half the wheel height or depth of submerged exhaust muffler exit, this time only you can do is to pass, because you simply make life difficult for the car.
Is familiar with the above section of road in the city, rain water is generally not too deep, but if encountered a large area of stagnant water, not familiar with the local traffic, the best is the bypass, do not frantically wade.
In Zijia You Or, rural roads, have to wade, they should not worry. First, look closely you wading through the water, if the current is a stream, then to remember, before the advent of the mountain torrents, or turn around quickly to make decisions in the past. If only because the rain formed a water-intensive, but a more uniform surface open and a small wave Department, are generally shallow end of the gravel layer, is trying to pass.
Regardless of where the rain should slow down a little, if no time to brake, saw a direct rushed into the water, then say nothing of the.
In the field, dirt road is very dangerous, as rain soaked subgrade, curb very easy to collapse, caused by rollover accidents is so, when driving to the dirt road, especially to avoid open on both sides, the middle to go along. See the front of the case have been landslides, and do not, and their gambling, we must not hesitate to contact the rescue, according to later try to return or remain in place.
Also, rainy days where the roads are too wet, high-speed Tire Outer layer of water film formation, to separate the tires and the road, so in this case the movement of vehicles on the road is hop hop, the feeling is significantly reduced friction, in order to turn this situation would be slow in, then gently turn the steering wheel, or else there will be overturned.
Above simply said, wading and the road turned to note the following talk about driving distance, windows, headlights importance.
Theory from moving about the safety of the vehicle and keeping a distance should be one-thousandth of the speed of your car, that is if the vehicle to 100 km / h, then the right lane with a car space is 100 meters, and if the rainy day, then this distance would also like to extend the half, which is calculated through scientific value, the driver friends do not want to challenge the limit, sometimes half a meter’s distance is the death industry.

A mass airflow sensor.
A mass air flow sensor is used to find out the mass of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and use of a turbocharger and this is an ideal application for a mass sensor. (See stoichiometry and ideal gas law.)
There are two common types of mass airflow sensors in usage on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with an additional sensor or two, the engine’s air mass flow rate can be accurately determined.
Both approaches are used almost exclusively on electronic fuel injection (EFI) engines. Both sensor designs output a 0.0- 5.0 volt or a pulse-width modulation (PWM) signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature (IAT) sensor incorporated into their housings.
When a MAF is used in conjunction with an oxygen sensor, the engine’s air/fuel ratio can be controlled very accurately. The MAF sensor provides the open-loop predicted air flow information (the measured air flow) to the ECU, and the oxygen sensor provides closed-loop feedback in order to make minor corrections to the predicted air mass. Also see MAP sensor.
Vane meter sensor
This section does not cite any references or sources.
Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (November 2009)
A vane, or paddle, projects into the engine intake air stream on a spring-loaded arm. The vane moves in proportion to the airflow, and a voltage is generated in proportion to the distance the vane moves, or the movement of the vane directly regulates the amount of fuel injected, as in the K-Jetronic system.
The vane moves because of the drag force of the air flow against it, it does not measure volume or mass directly. The drag force depends on air density, velocity and the shape of the vane, see drag equation.
The vane meter approach has some drawbacks:
it restricts airflow which limits engine output
its moving electrical or mechanical contacts can wear
finding a suitable mounting location within a confined engine compartment is problematic
the vane has to be oriented with respect to gravity.
Hot wire sensor (MAF)
This section does not cite any references or sources.
Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (November 2009)
A hot wire mass airflow sensor determines the mass of air flowing into the engine air intake system. The theory of operation of the hot wire mass airflow sensor is similar to that of the hot wire anemometer (which determines air velocity). The General Motors division (GM) was the first car company to use the hot wire sensor.[citation needed] This is achieved by heating a wire with an electric current that is suspended in the engine air stream, like a toaster wire. The wire’s electrical resistance increases as the wire temperature increases, which limits electrical current flowing through the circuit. When air flows past the wire, the wire cools, decreasing its resistance, which in turn allows more current to flow through the circuit. As more current flows, the wire temperature increases until the resistance reaches equilibrium again. The amount of current required to maintain the wire temperature is directly proportional to the mass of air flowing past the wire. The integrated electronic circuit converts the measurement of current into a voltage signal which is sent to the ECU.
If air density increases due to pressure increase or temperature drop, but the air volume remains constant, the denser air will remove more heat from the wire indicating a higher mass airflow. Unlike the vane meter’s paddle sensing element, the hot wire responds directly to air density. This sensor’s capabilities are well suited to support the gasoline combustion process which fundamentally responds to air mass, not air volume. (See stoichiometry.)
Some of the benefits of a hot-wire MAF compared to the older style vane meter are:
responds very quickly to changes in air flow
low airflow restriction
smaller overall package
less sensitive to mounting location and orientation
no moving parts improve its durability
less expensive
separate temperature and pressure sensors are not required (to determine air mass)
There are some drawbacks:
dirt and oil can contaminate the hot-wire deteriorating its accuracy
installation requires a laminar flow across the hot-wire
“Coldwire” sensor

The examples and perspective in this article deal primarily with the United States and do not represent a worldwide view of the subject. Please improve this article and discuss the issue on the talk page.
A Holden Commodore’s MAF sensor
The GM LS engine series (as well as others) use a “coldwire” MAF system (produced by AC Delco) where the inductance of a tiny sensor changes with the air mass flow over that sensor. The sensor is part of an oscillator circuit whose oscillation frequency changes with sensor inductance; hence the frequency is related to the amount of air (cubic feet per minute) passing over the unit. This oscillating electrical signal is then fed to the car’s ECU. These MAF units (such as the one pictured) have 3 pins, denoted +, – and F. F carries the square-wave frequency between – and F. They are powered by +5 VDC from the ECU’s regulated power supply.
The mesh on the MAF is used to smooth out airflow to ensure the sensors have the best chance of a steady reading. It is not used for measuring the air flow per se. In situations where owners use oiled-gauze air filters, it is possible for excess oil to coat the MAF sensor and skew its readings. Indeed, General Motors has issued a Technical Service Bulletin, indicating problems from rough idle all the way to possible transmission damage resulting from the contaminated sensors. To clean the delicate MAF sensor components, a specific MAF or Electronics Cleaner should be used, not carburetor or brake cleaner. These are alcohol or CFC-based solvents, rather than the harsh petroleum distillates used in the other cleaners… The sensors should be gently sprayed from a careful distance to avoid physically damaging them. Manufacturers claim that a simple but extremely reliable test to ensure correct functionality is to tap the unit with the back of a screwdriver while the car is running, and if this causes any changes in the output frequency then the unit should be discarded and an OEM replacement installed.
Krmn vortex sensor
Animation of the phenomenon. Courtesy, Cesareo de La Rosa Siqueira.
A Krmn vortex sensor works by setting up a laminar air stream. The air stream is disrupted by a vertical bow in the sensor. This causes a wake in the air stream and subsequently the wake will collapse repeatedly and cause Krmn vortexes. The frequency of the resulting air pressure oscillation is proportional to the air velocity.
These vortexes can either be read directly as a pressure pulse against a sensor, or they can be made to collide with a mirror which will then interrupt or transmit a reflected light beam to generate the pulses in response to the vortexes. The first type can only be used in pull thru air (prior to a turbo- or supercharger), while the second type could theoretically be used push or pull thru air (before or after a forced induction application like the previously mentioned super- or turbocharger). Instead of outputting a constant voltage modified by a resistance factor, this type of MAF outputs a frequency which must then be interpreted by the ECU. This type of MAF can be found on Mitsubishi Lancers/EVOs, all DSMs (Mitsubishi Eclipse, Eagle Talon, Plymouth Laser) and some Toyota’s and Lexuses.

Membrane sensor

Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (November 2009)
An emerging technology utilizes a very thin electronic membrane placed in the air stream. The membrane has a thin film temperature sensor printed on the upstream side, and one on the downstream side. A heater is integrated in the center of the membrane which maintains a constant temperature similar to the hot-wire approach. Without any airflow, the temperature profile across the membrane is uniform. When air flows across the membrane, the upstream side cools differently from the downstream side. The difference between the upstream and downstream temperature indicates the mass airflow. The thermal membrane sensor is also capable of measuring flow in both directions, which sometimes occur in pulsating situations. Technological progress allows this kind of sensor to be manufactured on the microscopic scale as microsensors using Microelectromechanical systems technology. Such a microsensor reaches a significantly higher speed and sensitivity compared with macroscopic approaches. See also MEMS sensor generations.

The Mass Air Flow (MAF) sensor senses the amount of incoming air (Volume) into the engine. This sensor does not regulate the incoming air, this is done by the engine throttle plates. The MAF merely senses incoming air and relates a signal to the ECM. Air flow sensors come in three types. The Vane Air Flow sensor, Hot Wire MAF sensor and Hot Film MAF sensor. They all perform the same function but their operation is quite different.
The VAF sensor measures the amount of air flow into the engine with a spring-loaded air flap/door attached to a variable resistor (potentiometer). VAF sensors measure air volume and not mass. The incoming air strikes or pushes against the internal air flap on the VAF sensor, which also moves the variable resistor sensing arm (wiper arm). As air flows into the engine the mechanical air flap rotates further, causing the wiper arm to contact a series of resistors, changing the voltage signal output.
The VAF sensor has an air-fuel adjustment screw, which opens or closes a small air passage on the side of the VAF sensor. This screw controls the air-fuel mixture by letting a metered amount of air flow past the air flap, thereby, leaning or richening the mixture. By turning the screw clockwise the mixture is enriched and counterclockwise the mixture is leaned. In addition to the regular air flow measuring function, some VAF sensors also employ an air temperature sensor (IAT sensor) and a fuel pump switch.
The IAT sensor is found inside the VAF casing and has the same electrical characteristics as a regular air temperature sensor. The VAF sensor flap also closes a set of contacts that activate the fuel pump relay coil (circuit opening relay). The contacts are actually closed as soon as the smallest amount of air pushes on the air flow flap. Once this happens the fuel pump starts running and the engine starts.
One of the main drawbacks of the VAF sensor is that it measures volume of air and not weight. As air temperature changes so does its weight. There are more air molecules present when the air is colder than when it is hotter. As air temperature decreases, more air is absorbed by the engine, so there are drastic changes needed in the air fuel ratio (depending on the temperature of the air). The air temperature sensor inside the VAF somewhat compensates by signaling the ECM of any changes in air temperature.
The HOT WIRE MAF sensor is a fully electronic unit. It senses the amount of air flow into the engine by measuring the amount of current needed to maintain a constant temperature through a very thin (70 micrometers) platinum hot wire. Hence the name hot wire MAF sensor. It also measures air by weight, since it takes into consideration the air temperature as well.
This sensor works as follows. As the air enters the intake manifold through the hot wire MAF sensor it cools down the platinum wire, which is heated at a very precise temperature. When the MAF circuitry senses the platinum wire cooling down it increases the amount of current flow through the hot wire trying to maintain a specific temperature. This varying current flow is then converted to a voltage output signal by the MAF electronic circuitry and is used as an air flow indicator by the ECM. Hot wire MAF sensors have a signal that is directly proportional to air flow. So as air flow increases so does its voltage signal output.
This sensor sometimes employs a mixture screw, but this screw is fully electronic and uses a variable resistor (potentiometer) instead of an air bypass screw. The screw needs more turns to achieve the desired results. A hot wire burn-off cleaning circuit is employed on some of these sensors. A burn-off relay applies a high current through the platinum hot wire after the vehicle is turned off for a second or so, thereby burning or vaporizing any contaminants that have stuck to the platinum hot wire element.
The HOT FILM MAF sensor works somewhat similar to the hot wire MAF sensor, but instead it usually outputs a frequency signal. This sensor uses a hot film-grid instead of a hot wire. It is commonly found in late 80 early 90 fuel injected vehicles. The output frequency is directly proportional to the amount of air entering the engine. So as air flow increases so does frequency. These sensors tend to cause intermittent problems due to internal electrical failures. The use of an oscilloscope is strongly recommended to check the output frequency of these sensors. Frequency distortion is also common when the sensor starts to fail. Many technicians in the field use a tap test with very conclusive results. Not all HFM systems output a frequency. In some cases, this sensor works by outputting a regular varying voltage signal.

VAF sensors are mechanical in nature. Their measuring element (wiper contact, pivot bushings and sensor resistors) get worn out over time. A binding air flap door is also a major problem with these sensors. The air flap mechanism is extremely precise and does not tolerate any misalignments. Always make sure that the air flap can travel freely all the way to its full open position. A broken air duct pipe will also render the VAF useless, since most of the air will be bypassed and enter though the broken duct hole. A thorough air duct check is always a good idea. The resistors also tend to wear out over time, sending the wrong voltage signal to the ECM. This will certainly throw off the air-fuel ratio.
The air temperature sensor and the fuel pump switch are the other reasons for VAF failures. This fuel pump switch activates the fuel pump relay and its contacts also wear down over time, causing a no start-no no-fuel pressure condition. A simple continuity test will quickly reveal a bad fuel pump switch. The air temperature sensor also follows the same electrical characteristics of a normal IAT sensor and the same ohms to temperature tables could be used for diagnostics.
Hot Wire MAF sensors are very prone to sensing wire element contamination. A condition referred to by many technicians as rowing hairs happens when debris, dirt from cheap air filters and outside air stick to the sensing wire element, shielding it from the incoming air. This shielding effect prevents the MAF sensor from correctly measuring the air flow and mass causing severe air-fuel ratio control problems. An ECM not in control while at pre-load is a strong indication of a dirty MAF.
In any fully electronic device, the electrical connections and circuitry fails after a certain lifespan of operation. An output signal voltage test will surely reveal a bad MAF sensor.
Hot Film MAF sensors tend to get electrical damage more often that the other type of sensors. The tap test ,as mentioned before, is a useful and simple procedure that usually reveals a bad hot film MAF sensor. Contamination or a broken air duct is also a problem for this type of sensor.
Manufacturers
Automotive air measurement sensors are manufactured by several manufacturers, including Continental VDO, Sensata Technologies, Bosch, Denso, Visteon, Delphi, AC Delco, Hitachi, Pierburg, Lwe Automobil, and Gill Sensors. The biggest manufacturers are Bosch, Siemens VDO and Pierburg.
Laminar flow elements

Laminar flow elements measure the mass flow of gases directly. They operate on the principle that, given laminar flow, the pressure difference across a pipe is linear to the flow rate. Laminar flow conditions are present in a gas when the Reynolds number of the gas is below the critical figure. The viscosity of the fluid must be compensated for in the result. Laminar flow elements are usual constructed form a large number of parallel pipes to achieve the required flow rating.

Jaguar C-X75 Turbo Hybrid:
Seventieth birthday Jaguar cars of the same name company decided to mention being a stunning car. The new owner, India’s Tata, wants to demonstrate that I was able to preserve the spirit of well-known brand, founded its founder Sir William Lyons. Of course, a passion for speed is the main theme of the developers of fresh Jaguar – but even this shows a conceptual C-X75, presented at the Salon in Paris. But it’s not so much in the feelings and style: this concept gives to the same original hybrid power train that combines electric motors and gas turbines. Jaguar confirms that the speed and grandeur of a very well mixed with concern for the environment.
However, not so often spoils the public Jaguar cars concept-penalties. Hence until this fall was the final C-XF in 2007. Perhaps He vividly embodies a descent in 2 serial model: beautiful small-sized (by the standards of Jaguar) XF, made its debut through a few months and has received volumes of the concept and the very idea, and elegant flagship brand XJ (debut in 2009), to whom inherited the distinctive headlights. Furthermore And now – just a triumph: C-X75, made to commemorate the birthday.
It seemed company Swallow Sidecar, begins with the production of biker carriages in the late 20 of the last century broke on outsiders body assembly chassis, and then – and their own machines. And of course in 1935, she appeared a model implementedname Jaguar. However, this title is as follows reflects the thoughts nimble and elegant cars that the company itself just had to accept it. In any case, this helped not at all a pleasant coincidence. Perhaps since 1934, the official title of the company was incomplete, SS cars – so “hidden” reference to the bikers’ wheelchairs, and the letters SS were used in the model designation. And here in Germany in those years, these letters made use of a completely different organization with correspondence way too little anyone could please – and in 1945 the British company acquired its own name the most successful models. Finally, it is how the Jaguar Cars Ltd. It seems that in 1945, she regained a one-time creation of cars, interrupted by the war in the forties.
I hope for the outline of the C-X75 as it follows clearly that the artists were inspired by historical models. Thus, direct ancestors of the hybrid concept, Ian Callum, Design Director for Jaguar, XJ13 calls in 1966, intended for racing at Le Mans. So, sure, this is also faster than the concept or design, he never took part in the competitions. But intended for his V-shaped 12-cylinder engine was the basis for the production of engines known Jaguar E-type. By the way, Callum calls XJ13 “most attractive Jaguar”. Perhaps, so it is not very powerful, that there is inside.
Probably the first turbo-electric but C-X75 is a boast than to share content. They say it’s a Jaguar with a hybrid drive, submitted by the public. In the end, in early 2010 the company erected a model of a hybrid car based on XJ named Limo Green, although its key purpose was supposedly test drive, rather than presentation of the latest style, and its no one put. C-X75 develops the idea of a hybrid – as should the elegant sports car. In general, He outright four electric motors, each of which develops power of 195 liters with … – Total 780! And these cars are absolutely suitable informal, although fully recognized stereotypes super car: the maximum speed of 330 km / h (205 miles per hour), and dispersal to weave for 3,4 seconds. Probably Round Table miles per hour (160 kph) as it gathers for its point of view round 5,5 seconds.
Fortunately, Well, the dynamics of electric-drive is now one tiny surprise: good acceleration, we see including the trolley … just speed in his other appearances, and not so encouraging. In fact, electric motor is almost an exemplary response, he develops very highest torque at low revs episode. For example, a 4 engine C-X75 1600 NM are doing. And apparently for petrol cars and super sto0 – a good effect. Therefore, the actuator does not have a need in the box and provides a model dispersal. I really electric other difficulties: the battery is currently too considerable and languorous. Apparently this dilemma and decide by a hybrid drive. Moreover Only promising hybrids, in distinction from the more closely we are popular Lexus, Toyota, Mercedes-Benz and others, not the electric motor can help ordinary motor and internal combustion engine used to recharge the batteries. It is so manufactured and C-X75. But this since Jaguar – and instead of the usual small gasoline or diesel engine there are two gas turbines!
On the other hand compact and not heavy (just under 35 kg) units of Bladon Jets to spin up to 80,000 revolutions per minute and delivers power to 94 liters with … any. In short, they work only on battery power, and they do not have to virtually any transmissions. On the contrary I have turbines as well as one other advantage: the fuel is burnt in an appropriate mode, and may do in the absence of any catalytic converters. It turned out that stocks of gasoline to 60 liters. enough, that car had a chance to go up to 900 km! On pure electric drive C-X75 is able to resolve 110 km, which still is good. Well, in principle, but may leave: wound per day own 50-100 km, per night and the battery from the mains (to achieve the desired result missing 6 hours), and again forward. And now Well if must move far away, then can fill the tank. Naturally, in a suburban route the exhaust gases is not as bad as in town. But suddenly turbines are superior: they throw no more than 28 grams of carbon dioxide per hundred kilometers. So is four times less than the motor super economical city car. In essence And it’s obviously not so well: Jaguar closer notification to the plan to release to market a hybrid car in 2011. And yet, so that C-X75, it is likely many times closer to mass production than is possible to estimate. Sure Shortly before the opening of the Paris Motor Show, where he was presented this concept, Tata bought a package promotions producer turbine of Bladon Jets. Consequently, of course, the turbine is excellent look at the heap. But the hybrid version of flagship Jaguar XJ their whistles will be absolutely relevant. And really like silent electric drive.
Anyway no current unit to ensure ecology and economy of one drive is incredible. You see And if the question of speed, relevance is not so much horsepower and newton-meters. At least, and here is the way sports skill Jaguar. Everything turns out to be in motion: aluminum and carbon fiber lower the weight of the body, whose shape is licked for the least anti-air. Nevertheless, at speeds under 300 mph solely on aerodynamic counter to spend up to 300 liters with …! By the way, here a little bit can help release turbines: the flow of exhaust gases out a one-time over mixer, reinforcing the result of the Venture, thanks Whom accelerating air createslow pressure under the body and pressed power.
C-X75 – sparkling example of what true love does not harm the car care about clean air. Actually a good car is almost always absolute in all respects. And in fact a perfect look so plausible, that leaves no one indifferent. Incidentally as Jaguar C-X75.

Saving Money on Gas – The Scoop on Products and Services
Article by Rick Chapo
As gas prices skyrocket and are forecasted to continue doing so, saving money on your fuels costs is becoming very important. Here is what you really need to save a few bucks.
Saving Money on Gas – The Scoop on Products and Services
The idea of improving your fuel economy by ten percent wasn’t much to get excited about when gas cost .75 a galloon. With some areas, such as San Diego, approaching .00 a gallon, a ten or twenty percent improvement starts to look very attractive. Most products claiming to help your mileage, however, are junk. On the other hand, certain steps and products can make a big difference.
Fuel injector cleaners are hardly new products on the market, but they can significantly improve your miles per galloon. Over time, fuel injectors get gummed up which means they do not fire at the correct time nor produce the correct amount of gas flow. You might think this would help your mileage since less gas is going in, but the opposite is true. The same goes for fuel filters. Replace the filters yourself and add a fuel injector cleaner the next time you are at the pump.
Air filters are another area where you can save some cash on gas. For an engine to work efficiently, it needs the correct amount of air flow that it was originally designed for. Dirty air filters throw this balance askew. Replace your air filter and you should see better fuel efficiency. You do not need to buy after market air filters because they actually will introduce too much air to the engine, making it inefficient.
One of the biggest areas you can attack to improve your mileage is the timing of your engine. Stick to the recommendations of your manufacturer, but use high end NGK spark plugs. They maintain their settings and will fire consistently throughout their life. Replacing your spark plugs should be done in concert with a tune up, another step that will increase your mileage by as much as 20 percent.
Although not a product, tire alignment is a big issue when it comes to gas mileage. If your tires are out of alignment, the friction coefficient between them and the road increases dramatically. This means it requires more engine power and gas to push the skewed tires across the road. Get them aligned and you will see immediate mileage improvement and a better ride. On top of this, make absolutely sure your tires have the correct air pressure as designated by the car manufacturer, not the tire manufacturer.
There is a lot of advice being offered on how to save money on gas, much of it so vague as to be useless. Take these steps, however, and you will see marked improvement and save some serious cash in the long run.
Had a go at gas flowing my shovel heads, i used a dremel as i found it easier to use than the flexible drill shaft. I cleaned up the rough casting walls for a more efficient flow of the gases.

Managing The Reverse Flow: Speeding Recalls And Returns With Radio Frequency Identification
Synopsis
Why are big retailers like Wal-Mart, Best Buy, and Target in the United States and Metro and Tesco in Europe so excited about RFID (Radio Frequency Identification)? Why is the US Defense Department mandating that RFID be used throughout its global supply network? Why are major pharmaceutical manufacturers (like Pfizer, Purdue Pharma, and GlaxoSmithKline) and drug wholesalers (including AmerisourceBergen, Cardinal Health and HD Smith) embracing RFID for its track-and-trace capabilities? In short, it is because of the visibility that RFID gives to organizations – visibility that is needed and expected in today’s increasingly fast-paced, interconnected and competitive world.
Overview
From a strategic perspective, we increasingly live in what could be termed a “Google Earth” world. To draw upon this analogy, just think how much our lives have been transformed by the power of information. A decade or so ago, if we were looking for a specific address in an unfamiliar area, how would we find it? Well, it would most certainly be done in a low-tech manner, by asking for directions or stopping at a gas station or a convenience store to ask for help.
Five years ago, we began to use MapQuest and – to a lesser extent – other web-based navigation tools. This made it possible to leave our homes with a print-out that had complete, turn-by-turn directions from any point A to any point B. We then began to see in-car navigation systems like OnStar come of age, providing us graphical directions and even voice prompts telling us what road to take and where to exit, turn, and stop. Today, we can sit at our desktop or view a laptop propped on the passenger seat to use Google Earth and view incredibly detailed photos from the sky of exactly what we will see on the ground, enabling us to zoom in on the exact parking space of the building at the address we are heading to. Thus, for anywhere we could physically wish to go on the planet – from Boise to Baghdad – we can now expect to have incredible visibility and real-time information. We expect – and demand – to be able to instantly find the proverbial “needle in the haystack” anywhere, anytime.
RFID and the Retail Supply Chain
The same is becoming true – and necessary – in today’s retail supply chains. With the global supply chains necessary to stock Target’s store shelves in Wichita Falls or Walgreen’s in Memphis stretching back to Hong Kong, Managua and other far-flung locales, major retailers must seek to have global business intelligence systems in place, managing movements of goods from manufacturer through shipment to their distribution center, to the stock room, to the store shelf through checkout. But barcodes present a crucial limitation: whereas they can only identify a class of items – a type of box of cereal for example – RFID can uniquely identify the specific box of that cereal that you are holding at the moment or the dozen on the store shelf in front of you. The promise of RFID in retail is to provide ROI through increased sales, increased inventory availability, reduced stock-outs and labor cost savings and the ultimate “retail nirvana” – still probably a decade or so away – where every item is tagged with RFID and “smart stores” promise interactive shelves and “roll through” checkouts. All this is made possible through the increased visibility that RFID brings and the imagination to use this data to better manage retail operations.
Take a simple example – in-store promotions. Let’s say that for the Super Bowl, a major retailer and a major snack food supplier are cooperating on a promotion for tortilla chips and salsa. For the big game, the supplier had stocked the products in four different locations in the store – the snack food aisle, the middle of a major traffic aisle, a special display set-up on the adult beverage aisle, and point-of-purchase displays in the checkout aisles. In today’s present environment, with bags of chips and jars of hot sauce being identified through barcodes, while it would be possible to gauge the overall effectiveness of the campaign (i.e., sales were up X% over last year at the same time and Y% over a “normal” weekend), it would be impossible to really assess the true, operational-level results of the Super Bowl promotion.
Fast forward to the near future when the products are RFID tagged and uniquely identifiable, and the retailer and snack food company could dig into far deeper and richer sets of data to ascertain – with great precision – the campaign’s effectiveness. For instance, both parties could discover previously undiscoverable consumer behavior insights such as from which display the items were purchased, which combinations of items were bought (sizes, flavors, etc.), which promotional items were bought with other non-promotional items, and so on. Thus, from this simple example one can only imagine how the increased visibility can be used by retailers (and their supply chain and logistics partners) to create new ways of managing the entire extended enterprise.
RFID and Reverse Logistics
For all the excitement about the advantages that RFID will bring to the forward retail supply chain, the really untold story regards the benefits that the technology will bring to the reverse supply chain. How so? Let’s start at the store level. With each item individually identifiable, the reverse logistics operation can begin with far greater intelligence. Shelves and stock rooms can be scanned to locate expired items that should be discarded and unsold stock that should be returned to the manufacturer for credit and/or shipped to a reseller. Likewise, when an item is returned by a customer, the retailer can track the specific purchase history of the item (where, when, how it was bought). Thus, retailers should be able to immediately spot a fraudulent return, and in time, eliminate that problem, which costs retailers billions annually. In the same way, when an item is returned for warranty work, the specific history of that item can be compiled. For both the retailer and the manufacturer, this will add an “early warning system” for problem items with high return and defect rates, enabling them to pinpoint such concerns far more effectively and quickly than today’s return data.
Perhaps the most important reverse logistics benefit will be in the area of recalls. Today, when products are recalled, it’s a matter of recalling way, way more than necessary – just to be safe. The quintessential example of this is the 2000 recall of Bridgestone/Firestone SUV tires, which involved the recall and replacement of over 6 million tires on Ford Explorers and other like models. If RFID tagging had been in place, rather than the mass recall – and mass hysteria that resulted from it – Bridgestone/Firestone could have been much more precise in its recall and replacement effort, since the problem was deduced to be specific production runs on specific days at its plant in Decatur, Illinois. This would have enabled the company to replace perhaps thousands of tires rather than millions, saving it and Ford immeasurable losses in the marketplace from their damaged brands and reputations. The recall could have been made even more effective by focusing more on the South and West, where warmer temperatures were correlated to higher failure rates for the problem tires.
Recalls in the Pharmaceutical Sector
While product recalls are a concern across all consumer-facing industries, there can be no greater area of emphasis than in the pharmaceutical sector, where product recalls can be a matter of life and death. Indeed, drug recalls are becoming increasingly common. According to the most recent data from the US Food and Drug Administration’s Center for Drug Evaluation and Research, the number of recalls involving both prescription and non-prescription pharmaceuticals has doubled over the past decade.
The most infamous drug recall case was the Tylenol case of twenty-five years ago. In reaction to the news that consumers had died as a result of product tampering, Johnson & Johnson executives made the decision to recall all Tylenol products. In the long-run, the brand survived and thrived, but in the short-term, the recall had a devastating effect. In fact, Tylenol’s market share in pain relievers at the end of 1982 had fallen to 8%, down from well over a third of the market a year earlier.
Drug recalls are costly endeavors, as they involve much administrative and logistical effort to make sure that all suspect product is taken off store and stockroom shelves and out of distribution channels. They also take a marketing toll on the brand and the company, as unlike with Tylenol, some brands are taken off the market forever or never recover their former standing. In fact, a recent University of Wisconsin study estimates that while the demonstrable cost of the typical drug recall runs into the millions, the decline in shareholder value following a drug recall is twelve times that of the total expenses incurred by firms in conducting the recall, replacing the product, and handling litigation associated with the recall.
An e-Pedigree Standard
EPCGlobal announced earlier this year the development of a broad e-pedigree standard that will work not just for the drug industry, but across many product lines. Having an e-pedigree available will enable drug recalls to be targeted with far greater precision as opposed to the former, “clear the shelves” methods that had to be utilized. For example, in a recent recall of the injectable drug methotrexate, used in the treatment of certain types of cancers and psoriasis, US Oncology was able to use pedigree data to target the recall to only those practices that had received a specific lot, making the process quick and effective.
Thus, in the future, when recalls happen, whether it be for pharmaceuticals (as with the recent Perrigo recall of store-branded acetaminophen) or suspect food items, the recalls can be accomplished with far more precision and speed than in the past, thanks to RFID tagging. Retailers can quickly separate cartons and individual units of recalled items from their retail shelves, stockrooms, and distribution centers, eliminating the need for hand searching for the suspect lots of goods. Manufacturers can also be more certain as to the overall completeness and effectiveness of their recall efforts, with new metrics and abilities to analyze the incoming items.
Finally, aside from drug recalls that occur from a specific safety or public health concern, the pharmaceutical companies must absorb costs estimated at exceeding billion annually from the return of outdated and overstocked products. Both at the store and wholesale level, there would be far greater ability to better manage inventory. Lucy Deus, vice president of Product Development for SupplyScape, recently commented that for all parties in the pharmaceutical supply chain, the direct visibility they will have will enable them to better manage shelf life and expiration dates. Also, in regards to managing expiration dates, analysts have projected that if RFID labeling is combined with sensor technology, products could have rolling expiration dates, which could give updated estimates on product usability. For instance, if a drug shipment endures extreme heat conditions during transit, or if a power outage during a blizzard causes products on the shelf to be exposed to harsh cold, the expiration date on the drug bottle or vial could be shortened according to pre-determined algorithms based on research. They could even be instructed to immediately expire if the conditions exceeded certain thresholds.
Analysis
As we consider the ROI of RFID, many times vendors and solutions providers miss the mark in terms of being able to portray what the RFID-enabled future will look like. We worry too much about the small stuff of today’s issues – read rates, tag prices, tag reliability and availability, etc. However, while these mechanical and operational issues indeed need to be worked out quickly, as we look not so far down the road, there is a bright future ahead with incredible, unanticipated returns on the investment in RFID technology from every perspective along consumer-facing supply chains – much of it to be gained in the reverse flow of products. It will be up to those in the auto ID industry to make the case that in the “Google Earth” world, RFID is the right technology to provide the real-time visibility that is vital to effective product management in today’s global economy, enabling retailers, distributors and wholesalers to find the unsold, suspect, outdated, or recalled needle in the haystack in a quick, efficient, and cost-effective manner. Such is managing in the new, new economy, being made possible with RFID.

Absolutely sure customers be aware of whenever his or her cars and trucks desire essential oil variations or his or her’s from the must be turned. Wal-Mart generally reminds you by putting a ticket in the still left team of your windscreen. But which informs us whenever we have to change this moment weight loss belt? In the event we were sharp we would look and feel up within motor vehicle guidebook. Many u . s . as i am were not sure not wearing running shoes would have to be evolved every last 60 to 70,500 cientos. Sorry to say I actually compensated the retail price.

Ukraines Out of control Government once again refuses to let gas flow to Europe, but Europe’s Govts decline to Pressure Ukraine to let Russian gas transit disregarding suffering of millions of people and damage to already suffering Economies on the whole Continent. Ukrainian opposition calls for impeachment of Yushchenko 14:23 | 13/ 01/ 2009 KIEV, January 13 (RIA Novosti) – Ukraine’s biggest opposition faction started on Tuesday procedures to impeach President Viktor Yushchenko, and also called for the dismissal of Prime Minister Yulia Tymoshenko’s government. “We demand the immediate resignation of the government and the start of procedures to impeach the president,” Viktor Yanukovych, the leader of the Party of Regions, said, addressing an extraordinary session of parliament devoted to the current gas dispute between Russia and Ukraine. He was supported by the Ukrainian Communist Party. Yushchenko, whose popularity has slumped to 2.4% according to the results of a poll published on Monday, did not attend the Supreme Rada session. Tymoshenko was, however, present. Russia cut off shipments of natural gas to Ukraine after talks on outstanding debt and a gas price for 2009 broke down on New Year’s Eve. The gas conflict led to a complete breakdown in Russian gas supplies to Europe via Ukraine, which transits around 80% of Russia’s gas exports to EU countries. Yanukovych said that because of the “irresponsible” position of the government, Ukraine was facing a threat to its …
The Ultrasonic Gas Flow Meter
While it seems like a simple question, an ultrasonic gas flow meter is a very complicated piece of equipment. These devices are used to measure the flow of gases and fluids through a pipe. While some are fixed, they also come in an ultrasonic flow meter portable version. These units are great for getting a quick reading and are almost as accurate as the fixed version.
Features and Functions of a Ultrasonic Gas Flow Meter
The units are generally non intrusive so that they will not affect the flow running through the pipe being measured. There are several different methods for measuring flow from transit time correlation to concurrent transit time, pulsed Doppler and continuous wave Doppler.
Not all applications are the same and it is important to be able to offer flow meters that suit the actual requirements. The use of non intrusive measuring devices has increased in popularity over the last ten years saving valuable time and in addition preventing the contamination of surrounding areas.
The ultrasonic gas flow meter is incredibly sensitive piece of equipment and a good one will be able to tell within a very fine area how much gas is flowing.
These clamp on ultrasonic gas flow meters can measure the erosive, corrosive, toxic, high purity sterile gases or any application where penetrating the pipe wall is undesirable. Theses meters generally will have a wide range and the meters will have no wetted or moving parts for virtually no maintenance. A clamp on ultrasonic gas flow meter will not cause any drop in pressure, as it resides outside the pipe.
For the most part meters will also offer the option to export there readings directly to a computer.
This can be done through any number of auxiliary inputs and is useful to monitor and compare data from multiple ultrasonic gas flow meters.
As you can see a gas flow meter is much more complicated than it would first appear. They come in a variety of forms and can be used in a variety of applications. It is up to you the user to decide what the best application for your ultrasonic gas flow meter is, and which one will best fit.
Whether it is a fixed or portable unit, whether it measures multiple values simultaneously or simply does individual ones is up to you. The important thing is that these devices no longer need to be placed inside the pipe and you can safely and reliable measure the flow with no harm to the outlying areas.
