Air flow meter description
Mass air flow meter is an air flow sensor, also known as MAF sensor, which is an important part of the engine control system. Generally located in the plastic housing between the engine and the air filter. It is used to measure the engine intake, and to provide engine control system in the form ofelectric signal. The engine control system according the signal gives the accurate fuel injection rate to obtain the best air fuel ratio. Air fuel ratio determines the engine's power, economy and exhaust emissions targets, must be controlled precisely. Therefore, the quality of air mass flow meter is very important..
