1.柴油机燃油系统有哪些部件组成? 答:柴油机燃油系统由柴油箱、粗滤器、输油泵、低压油管、细滤器、喷油泵、高压油管、喷油器及回油管组成。燃油系进、回油过程,均应在密封环节中进行,任何部位不得有泄漏、堵塞等现象。否则将无法保证燃油系统正常工作。从柴油箱到喷油泵进油口,这段油压是由输油泵建立起来的,压力一般在294千帕以下,称为低压油路。从喷油泵到喷油器,供油压力较高,一般在9800千帕以上,称为高压油路。当喷油器回油螺钉及喷
1. Diesel fuel system which components? A: Diesel fuel system by the diesel tank, strainer, oil pump, low pressure tubing, fine filter, fuel pump, high pressure tubing, injector and return pipe composition. Fuel into the back to the oil process, should be carried out in the sealing section, no parts may have leaks, clogging and so on. Otherwise there will be no guarantee that the fuel system will work properly. From the diesel tank to the injection pump inlet, this section is set by the oil pump pressure, the pressure is generally below 294 kPa, known as low-pressure oil. From the fuel pump to the injector, a higher pressure for oil supply, generally more than 9800 kPa, called high-pressure oil. When the injector oil return screw and spray
