Zero restrictions in hoarding air plus enough fuel flow, only with an air mass meter.
Automotive experts say that the amount of air-fuel mixture should always be right, but how do you really know if the mixture amount is right? Well, that's the reason your auto has the air mass meter. This metering device measures the mass of air flowing into the engine. Based on this measurement, the engine computer unit (ECU) bases its calculations as to the amount of fuel the injector will atomize into the intake valve. Turns out, an efficiently working air mass flow meter equals better MPG and fuel economy.
An air mass meter is a plastic tube mounted right after the air box and through which the filtered air freely flows. As the air passes through it, a sensor measures the air mass. Electrical wires attached to the meter then transmit the measurement to the ECU for calculation. This meter is crafted to last the life of a vehicle, but micro particulates seeping through, coming together with the filtered air, may build up in and around it over time and render it useless.
There are different air mass meters for different applications: vane meter, cold wire, membrane, and hotwire meter. Among these, only the last three directly measure the mass of air going into the engine. The vane meter measures air volume, temperature, and pressure to determine density. Air mass is then calculated from the result. Whichever air mass meter is mounted in your auto, see to it that you keep it in shape for a long and reliable service.

  • Mass Air Flow Sensor: Just the Facts 21 December 2012

    Your vehicle's engine can't make use of even the most expensive fuel without one basic element: air. For proper fuel combustion, the engine needs a mixture with the right amounts of air and fuel.And how do you make sure that the mixture sent to the engine's cylinders contains the ideal fuel–air ratio? Well, your best bet is to equip your vehicle with a reliable air mass meter. The air mass meter is a plastic tube usually mounted behind the air filter.The meter's interior contains sensors that determine how much air enters the engine bay. Attached to the meter are wires that relay the information to the vehicle's engine control unit (ECU), which in turn control fuel injection.Through information detected by the air mass meter, the ECU releases the right amount of fuel relative to the amount of air in the engine. See how helpful this meter can be? Should you want one for your vehicle, browse our catalogs.Various meters brands and designs are available here at Car Parts for you to choose from.

  • Important Facts You Need to Know About Mass Air Flow Sensor 10 October 2012

    Better fuel combustion is just a click away/ Install only quality Mass Air Flow Sensor, Mass Air Flow Sensor Plug, and replacement Mass Airflow Sensor.
    The 1980s may have given us a lot of things to cringe about. There's the introduction of new wave music, weird hairdos, and outrageous fashion statements. However, the decade did provide us with something to smile about when the fuel injection system officially replaced carburetors. As a result, a number of components were developed to complement this system. One of these components is the Mass Air Flow Sensor.
    This sensor is considered as an important part of your vehicle's electronic fuel injection system. It's installed in the intake air duct between the air filter and engine. This component measures and records how much air your fuel-injected engine is using. Once it's been able to collect the needed data, the mass air flow sensor plug then transmits it to your engine control unit or ECU. Using this information, the ECU proceeds to calculate the exact amount of fuel that will be injected into your engine's cylinders.
    With the right amount of air, the engine can have superior performance. That's why you need a Mass Air Flow Sensor to calculate the right amount of air for your fuel-injected engine. This will enable your car to enhance combustion and reduce carbon emission. If you don't have this sensor yet, you can easily find a wide selection of mass air flow sensors for your car on the Web.

  • The Automobile Basics: Mass Air Flow Sensor 03 October 2012

    With the advent of fuel injection systems in modern times, vehicles are now outfitted with mass air flow sensors. A mass air flow sensor functions as a gauge which measures, true to its name, the amount of air which flows into your car's engine. It works hand in hand with the ECM. The ECM, which stands for Electronic Control Module, is the on board computer used by the car which is responsible for determining the metering of fuel and the timing of the injection as a response to parameters such as crankshaft position. As the mass air flow sensor takes the reading of the incoming air, it subsequently sends the gathered data to the ECM for it to provide a proper response. The end result is better performance from your car in the form of optimized fuel combustion as well as minimal emission. However, a malfunctioning mass air sensor can be very bad news for you. Such results of bad mass air sensors are poor acceleration, misfiring, and stalling during cases when the engine is cold among other things. To prevent such maladies from ailing your trusty ride, replace dysfunctional mass air flow sensors immediately with prime-grade quality replacements from CarParts. Check out our catalog now!
