The pump behind the generator of the Dongfeng Ruiqi van is called a vacuum pump.
1. The braking system of a family car generally relies on hydraulic pressure as a means of transmission. Compared to the air brake system which can provide power, it requires an assist system which assists the driver's braking. and the vacuum brake assist system can also be called a vacuum servo system.
2. For vehicles with diesel engines, since their engines use compression ignition, the same level of vacuum pressure cannot be provided at the intake bypass pipes, requiring a vacuum pump that can provide a source of vacuum. Used in addition, the vehicle engine, which is designed to meet certain vehicle emissions and environmental protection requirements, also needs it toprovide sufficient vacuum source to ensure that the car can operate normally.
3. Its main function is to use the vacuum generated by the engine when running, and then provide sufficient assistance to the driver when pressing the brakes, so that the driver is lighter. and easier to use when applying the brakes, but once the vacuum pump is damaged, it lacks some power, so it will feel heavier when the brakes are applied. In addition, the braking effect will be reduced and. sometimes it even fails, which means the vacuum pump is damaged.
