    Abstract: Based on the analysis of diesel engine’s working process, this paper has built a steady–state simulation program of diesel engine with Matlab/Simulink software, realizing the modularity of each model program of the diesel engine. Fixing certain type of turbocharged diesel engine as the study subject, this paper has taken simulation calculation on different loads of the diesel engine and the calculation results basically agreed with the experimental results, thus verifying the accuracy of Simulink. On this basis, using GUIDE interface provided by MATLAB to design the environment, this paper has designed GUI man-machine exchange interface of Simulink. GUI interface can control Simulink and parameter setting, and display different simulation results under different working conditions, thus making the program more flexible and efficient, and improving the efficiency of the simulation.
