Product Description
Automobile air flowmeter is a sensor for measuring the air flow introduced into the engine, and it is an important part of the engine control system. The main function of the air flow meter is to monitor the amount of air introduced into the engine, so as to control the fuel injection amount and maintain the ideal air-fuel ratio, thus ensuring the normal operation of the engine.
The working principle of air flowmeter is as follows:
1. The air flowmeter is usually installed in the air inlet pipeline, and the air enters the engine through the flowmeter.
2. The air flow meter contains a sensor, usually a hot wire sensor or a hot film sensor. When air flows through the sensor, the sensor is heated and the resistance changes.
3. By measuring the resistance change of the sensor, the air flow meter can calculate the air flow introduced into the engine.
4. The air flow meter sends the measured air flow information to the engine control unit (ECU), and the ECU adjusts the fuel injection quantity according to the air flow information to maintain the ideal air-fuel ratio.
Generally speaking, the air flowmeter helps the engine control system to monitor and adjust the fuel injection in real time by measuring the air flow introduced into the engine, so as to ensure the normal operation of the engine and improve the fuel economy and emission performance. Therefore, the air flowmeter plays a vital role in engine performance and emission control.
