【Abstract】 The design conception of a new type of the electronic controlled common rail injection system with a hydraulic booster has been presented in this paper.The model of the injection system is established by using the Euler-Method.The whole process is divided into different parts,and the boundary conditions of each part are determined.The design parameters such as the boost ratio,the section area of magnetic valve,the area and number of injection holes are simulated to determine their effects on injection rate,and thus the optimized results are obtained.更多还原
