Oil pump nozzle maintenance
1, air filter is blocked.
2, whether the turbocharger is working properly, whether the compression pressure reaches the value, if it is an EFI engine, you can test whether the compression pressure is enough through the ECU.
3, whether the pipeline is broken or internal blistering caused by clogging.
4, the second cylinder does not work, in the case of oil pumps and valves are not a problem, check whether the injector is open, direct injection engine to check the injector springs, EFI engine to check whether the injector wires are energized with the solenoid valve is working properly. Finally whether the injector can be atomized normally, not atomized, the corresponding cylinder is not working.
Injection pump test bench is a diesel engine injection pump testing, adjustment and maintenance of specialized equipment. At present, the domestic manufacturers of injection pump test bench manufacturers in Shandong Tai'an, Henan Nanyang, and Jiangsu Wuxi and other places of production. Injector pump test bench as an injection pump debugging test equipment, in the manufacturing and maintenance of the injection pump test bench plays an important role. In recent years, with the increasingly wide range of diesel applications, oil pump nozzle technology continues to improve, injection pump manufacturers and maintenance industry on the technical requirements of the injection pump test bench is also higher and higher, resulting in the few domestic test bench manufacturers have to the world's advanced technology closer.
