| Abstract:Aiming at the phenomenon of high pressure fluctuation in the rail-injector connecting fuel pipe of the high pressure common rail system of a marine diesel engine, a simulation model of the common rail was built with the AMESim hydraulic simulation platform to study the influence factors of the pressure fluctuation peak. Based on the analysis results, the structural improvement scheme to reduce the pressure fluctuation peak was proposed, and the optimized scheme was tested and verified. The results show that the pressure fluctuation peak can be effectively reduced by arranging a throttling hole at the common rail outlet and optimize the inner diameter of pipe. |
