HD—180汽车配有带PT燃油系统的NTO—6—B孔明斯发动机,经一定时期使用后,工作中常常因PT燃油泵出现问题而引起发动机功率下降、油耗升高和工作不稳定等故障。因此,须对PT泵进行定期的检查和调整。 PT燃油泵较为理想的试验方法是在专用的PT泵试验台上进行。但在缺乏该设备的情况下,也可直接在发动机上进行检查和调整,此时需将发动机装在可以加负荷的测功机上。试
The HD-180 car is equipped with a NTO-6-B Kong Minsi engine with a PT fuel system. After a certain period of use, it often causes problems such as engine power drop, fuel consumption increase and unstable work during operation due to problems with the PT fuel pump . Therefore, the PT pump must be regularly inspected and adjusted. PT fuel pump is the ideal test method is in a dedicated PT pump test bench. However, in the absence of this equipment, it is also possible to check and adjust directly on the engine, in which case the engine needs to be mounted on a dynamometer that can be loaded. test
