在使用分配泵的进口或国产五十铃车上,如江铃、庆铃,为使柴油车能够迅速而完全地切断燃油。在分配泵泵壳上安装了燃油切断电磁阀,即我们平时所说的进油控制电磁阀,它由钥匙开关控制。在停车阶段,进油电磁阀不通电,电磁阀芯将进油油路堵死;在起动和发动机运行阶段,进油电磁阀通电,电磁阀芯在电磁吸力作用下被吸拉,进油通道打开,燃油进入分配泵泵腔。 但在分配泵泵壳的上中部,还可发现另外一个电磁阀,即冷起动
In imported or domestic Isuzu trucks that use distribution pumps, such as Jiangling and Qingling, fuel is cut off quickly and completely for diesel vehicles. In the distribution pump casing installed fuel cut off solenoid valve, that is, we usually said the inlet control solenoid valve, which is controlled by the key switch. In the parking phase, the inlet solenoid valve is not energized, the solenoid valve core will be blocked into the oil circuit; in the start-up and engine operation phase, the inlet solenoid valve is energized, the solenoid valve core is sucked and pulled by the action of electromagnetic attraction, Open, the fuel into the distribution pump chamber. However, in the middle of the distribution pump casing, you can also find another solenoid valve, cold start
