众所周知,现代汽车发动机都设计安装了真空管路系统,它和相关电控元件、机械装置配合,主要实现如下功能: 1.获取发动机进气歧管压力信息,控制发动机正常运转。如:MAP传感器、燃油压力调节器、真空点火提前装置等。 2.控制排气净化系统。如:燃油蒸发控制装置、EGR废气再循环装置、PCV曲轴箱通风装置等。
As we all know, modern automobile engines are designed and installed vacuum piping system, which and related electronic control components, mechanical devices, mainly to achieve the following functions: 1. Get the engine intake manifold pressure information to control the normal operation of the engine. Such as: MAP sensor, fuel pressure regulator, vacuum ignition advance device. 2. Control of exhaust gas purification system. Such as: fuel evaporation control device, EGR exhaust gas recirculation device, PCV crankcase ventilation and so on.
