Diesel Injector Fuel Injector 0445120321 Bosch for Case New Holland D20

Causes of Diesel Injector Failures
In the repair of diesel engine oil gnawing device. A part to be repaired usually has several or more damages and faults. Even some parts may not have reached the state of ultimate damage, but they still need to be overhauled and repaired. The article makes an in-depth analysis of the common failures of diesel fuel injectors, and through finite element calculations, it is concluded that the main reason for the frequent failures of diesel fuel injectors is the failure caused by diesel leakage at the nozzle end. After repairing and inspecting according to relevant regulations, Re-applied to agricultural machinery, the service life of agricultural machinery is increased by 7~12 times. The fuel injector of diesel engine is mainly composed of upper and lower parts, the upper part is the injector body, and the lower part is the nozzle. When disassembling, the injector bears a torque of 540 N·m.
During the repair process, it was found that there was serious scale in the water channel, which blocked more than half of the water channel as a whole, thus reducing the heat transfer efficiency of the fuel injector. Moreover, there are obvious oil stains on the plane, which means that the fuel injector of the diesel engine has an oil leakage accident. At the same time, there is a large amount of residue on the plane of the fuel injector. It can be seen that the installation process of the diesel engine fuel injector did not follow the relevant regulations and procedures. .
