分电器真空管的作用是,当发动机转速增高时,利用化油器喉管处的真空度来使分电器的点火提前角增大,以适应发动机的高转速,发挥汽车的有效功率。但是在实际工作中,我们经常发现一些驾驶或修理人员,一方面为减少维修保养的麻烦,另一方面,对真空管的作用缺乏必要的了解,因而将此真空管拆除,造成了以下的不良后果:1.分电器真空提前调节 Distributor vacuum tube role is that when the engine speed increases, the use of the vacuum at the carburetor throat to increase the distributor advance ignition angle in order to adapt to the high engine speed, the effective power of the car. However, in practice, we often find that some drivers or repairers, on the one hand, do not have the necessary knowledge about the function of the vacuum tube to reduce the inconvenience of maintenance and repair. Therefore, dismantling the vacuum tube has the following adverse consequences: 1. Sub-electrical vacuum regulation in advance
