因电预热塞钢球与阀座密封不严,柴油从这里被吸入进气管而漏入气缸,引起转速不稳甚至飞车的故障,本刊已有论述,这里再补充两个也是因电预热塞漏油而引起的故障。一是因柴油漏入气缸过多,而液体是不可压缩的,所以在起动时造成连杆顶弯。另一起事故是因蓄电池电不足,想拖拉起动机子,而被拖机车驱动轮却不能转圈。经检查,被拖机子的变速箱 Due to the electrical preheat plug ball and valve seat tightness, diesel is drawn into the intake pipe from here and leaking into the cylinder, causing speed instability and even the speed of the car, the article has been discussed here to add two because of electricity Hot plug leakage caused by the failure. First, due to excessive leakage of diesel fuel into the cylinder, and the liquid is incompressible, so start connecting rod caused by bending. Another accident is due to lack of battery power, want to drag the starter, and was towing the drive wheel can not circling. After checking, was tractor son gearbox
