Air Mass sensor - 0 280 217 517
Mass Air Flow Sensor (MAF): A key component in the engine management system that measures the amount of air entering the engine. This measurement allows the engine control unit (ECU) to calculate the optimal fuel-to-air ratio for efficient combustion. By ensuring precise air intake data, the MAF sensor helps enhance engine performance, fuel efficiency, and reduce emissions. Regular maintenance and cleaning of the MAF sensor are important to prevent performance issues and maintain optimal vehicle efficiency.
AIR MASS METER information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and the use of forced induction, which means that mass flow sensors are more appropriate than volumetric flow sensors for determining the quantity of intake air in each cylinder.
There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with additional sensors and inputs, an engine's ECU can determine the mass flow rate of intake air.
