Diesel Injector Fuel Injector 095000-6363 Denso Injector for Isuzu 4HK1 6HK1

Diesel engines are widely used in modern industrial fields and play an important role in promoting the development of modern civilization. As an enterprise producing diesel engines, Anhui Quanchai Power Co., Ltd. has been widely used throughout the country with its diesel engines due to its good performance. However, in order to ensure the effective operation of diesel engines, strengthening the understanding of the symptoms and causes of common problems is an important guarantee for improving the efficiency and safety of diesel engine operation. This paper takes the common fault problems of Anhui all-diesel diesel engine injectors as the object of exploration, and explains some maintenance measures for common problems.

Apparent characteristics of diesel engine injector problem Injector is a key component of diesel engine and one of the components with frequent failure problems. The occurrence of the injector problem is very easy to cause a series of effects on the diesel engine, from the increase in fuel consumption, the decrease in power, to the serious wear of the parts, etc., all indicate that the injector problem has a greater impact on the normal operation of the diesel engine. Taking the Anhui all-diesel diesel engine as an example, the apparent characteristics of the injector problem are very conspicuous, and are concentrated in the following aspects:

Cylinder "knocking sound" During the operation of the diesel engine, the cylinder injector fails, which in turn leads to a change in the amount of fuel injection in the cylinder. In practice, in the diesel engine working process, the injection pressure tends to change, making the injection pressure too high or too low. The injection pressure is too high, which will cause the injection pump plunger coupling and the injector to wear out early, and sometimes the high-pressure bamboo will be swollen and cracked, and the diesel engine will knock the cylinder when working.
