Product Description
The CAFS1000 Series MEMS Air Flow Sensor, also known as an air mass flow meter, is designed for use in modern automotive engine electronic fuel injection systems (EFI). Typically installed between the air filter and throttle body, this sensor measures the amount of air intake into the engine. The output signal serves as a key parameter for controlling fuel injection quantity in automotive EFI systems, influencing the engine's power, efficiency, and emission performance. To achieve optimal fuel-air mixtures under various operating conditions, the sensor accurately measures the air intake at every moment, providing essential data for the ECU (Engine Control Unit) to compute and regulate fuel injection. Therefore, the air flow sensor plays a crucial role in energy conservation and pollutant emission control in modern vehicles.
