Fuel System New Diesel Fuel Injection Pump Head Rotor 146401-4420 VE Head Rotor for Diesel Engine Parts

As an important vibration source of the entire vehicle, the engine's NVH level directly affects the NVH level of the entire vehicle, so it is necessary to control engine noise. According to the engine noise problem, the noise and vibration generated by the high-pressure diesel pump are analyzed. Mainly by optimizing the transmission path of high-pressure diesel pump vibration to reduce the transmission of vibration, thereby reducing noise.

As an important part of a diesel engine, the diesel engine fuel system consists of a fuel tank, a fuel pump, a coarse fuel filter, a fine fuel filter, a fuel injection pump, a fuel preheater, a fuel injector, a fuel delivery pipe and a pressure gauge. According to the different working conditions of the diesel engine, the diesel engine fuel system sprays a certain amount of fuel into the cylinder through the injector at a certain pressure, and fully mixes and burns it with the air in the cylinder, so that the chemical energy of the diesel is converted into Mechanical energy promotes the operation of the diesel engine and achieves power output.

When the diesel engine is running, it needs to be powerful, economical, and reliable. This requires stabilizing the diesel engine speed. The diesel engine speed is adjusted by changing the fuel supply amount. In actual locomotive work. Failures in the fuel system are inevitable. Therefore, only by troubleshooting common fuel system failures in a timely and effective manner can the operating efficiency of the diesel engine be improved. With the vigorous development of scientific technology, diagnostic instruments have become more advanced and accurate, and their functions can be significantly improved. Through instrument diagnostic technology, not only fault diagnosis can be completed, but also equipment operation conditions can be dynamically monitored, reducing the probability of equipment failure and improving Enterprise economic benefits. The high-pressure diesel pump diesel supply rack is an important component that changes the amount of diesel entering the combustion chamber. The rack meshes with the ring gear in the high-pressure diesel pump body. Through the left and right movement of the rack, the ring gear and the plunger are driven to rotate, changing the diesel supply time and diesel supply amount of the plunger couple to meet the needs of the diesel engine operating conditions.
