Abstract: The structural parameters of the high pressure common rail injector have an extremely important influence on the fuel injection performance of the diesel engine. This paper takes the high-pressure common rail injector as the research object, uses the AMESIM simulation software to simulate and analyze the high-pressure common rail injector, and optimizes the design and optimization of its four key structural parameters. After comparing the results of cycle fuel injection volume and fuel injection pattern before and after optimization, it was determined that the optimization plan was close to the actual demand value of the project, and the rationality of the optimization plan was determined.

Key words: High pressure common rail injector, Simulation analysis, Optimization design, AMESIM
