(4) Improve the cleanliness of the fuel injector: the use of more advanced deburring equipment to remove the fuel injector body, the fuel injector nozzle processing generated in the burr, the use of ultrasonic cleaning machine to improve the cleaning quality; Run in enough time before leaving the factory, disassemble and clean after the end of the run in

4 Closing Remarks

The opening pressure drop problem of the injector is a problem for many years. For example, the quality of the spring at home and abroad is larger, and the fatigue relaxation cannot be eliminated fundamentally. The problem of cleanliness has been difficult to solve, and it is impossible to completely solve the problem of pressure drop. This requires users to adjust and maintain the fuel injector frequently, so that the diesel engine can achieve the best working condition.

1 diesel engine "flying speed" reasons and elimination measures "flying speed" refers to the diesel engine speed out of control, rapid rise more than the normal speed of the critical phenomenon, "flying speed" issued a sharp scream, if not stopped in time, it will cause crankshaft, connecting rod and other pull break, even the body, flywheel blast etc. Causes of diesel engine "racing" reasons: ① governor failure, rack in the maximum oil supply position stuck; ② The tightness of the compression system is not strict, and the oil is burned seriously. ③ Occurs when the load is suddenly removed for some reasons in load work. Once the diesel engine occurs "racing", extraordinary measures can be taken to force the diesel engine to stall and stop: ① the decompression handle to the decompression position; (2) Pull out the cyclone cover, tightly block the air filter inlet with the palm of the hand or clothing, and block the air suction cylinder; Pull out the oil pipeline, loosen the high-pressure oil pipe nut with a wrench, cut off the oil circuit and stop the oil supply. This sometimes doesn't work because flying cars tend to burn oil
