| Abstract: | According to the characteristics of diesel engine and on basis of choosing the computational boundary conditions, the mathematics model of diesel operating process was set up, a simulation program for diesel operating process calculation by MATLAB was developed, and simulating calculation to CY4102BZLQ diesel operating process was carried out. The curves of gas pressure, gas temperature and gas mass in cylinder are obtained. The comparison between results of simulation calculation and experiment results shows that simulation computation program is accurate and feasible. |
