CAFS1000C Wide Flow Rate Range: 0-60 m/s High Impact Resistance: Withstands 100g impact, commonly known as an air flow meter, is a crucial component in modern automotive electronic control fuel injection systems (EFI). Typically installed in the intake tract between the air filter and throttle body, this sensor measures the amount of air being drawn into the engine. The output signal from the sensor is a primary parameter for controlling fuel injection in the engine management system, directly influencing the engine's power performance, fuel economy, and emission standards.

To achieve the optimal fuel mixture concentration under various operating conditions, the EFI engine must accurately measure the intake air volume in real-time and calculate the necessary fuel injection using the electronic control unit (ECU). Consequently, the air flow sensor is vital for improving energy efficiency and reducing pollutant emissions in modern vehicles.

The CAFS1000C Series has been widely adopted in the automotive and related industries due to its high reliability, stability, accuracy, and cost-effectiveness. The product's application potential is vast.
