汽油泵继电器是一种电子设备,它在汽车引擎启动时起到了关键作用。它的主要功能是控制汽油泵的电源,确保引擎可以正常运转。
汽油泵继电器通常安装在汽车的引擎控制模块(ECM)中。当启动汽车引擎时,ECM会向汽油泵继电器发送信号,以启动汽油泵并将燃料输送到引擎中。一旦引擎启动,ECM将停止向汽油泵继电器发送信号,从而停止汽油泵的运转。
如果汽油泵继电器出现故障,汽车引擎可能无法正常启动或运行。因此,定期检查汽油泵继电器是否正常工作非常重要。

The fuel pump relay is an electronic device that plays a crucial role in starting the car engine. Its main function is to control the power supply of the fuel pump and ensure that the engine can operate normally.
The fuel pump relay is usually installed in the engine control module (ECM) of the car. When starting the car engine, the ECM sends a signal to the fuel pump relay to start the fuel pump and deliver fuel to the engine. Once the engine is started, the ECM stops sending signals to the fuel pump relay, thereby stopping the operation of the fuel pump.
If the fuel pump relay fails, the car engine may not start or run properly. Therefore, it is important to regularly check whether the fuel pump relay is working properly.
