How does the injector of a common rail system differ from most other injectors?

Common rail injectors utilize a high-pressure fuel rail that provides fuel to the individual injectors. Unlike with unit injectors, the rail maintains the fuel at a constant, high pressure that is necessary for injection. ... The higher pressure capabilities also allow for increased efficiency and improved emissions.

In view of the durability of needle valve coupling in electronic control fuel injection system, the principle of a certain type of electronic control injector is described, and the possible failure mechanism of needle valve coupling is analyzed. Through modeling and simulation, the impact fatigue life is predicted and analyzed mainly on the basis of mechanism analysis. The failure mechanism and the accuracy of life prediction of needle valve coupling are verified by experiments. The experimental results prove that the durability analysis model is effective, which can provide reference for the durability analysis of similar components, and provide support for the life design optimization of electronic fuel injectors.
