Abstract: The thermodynamic performance of a diesel engine with heat transfer and friction term losses is analysed. This study deals with the numerical simulation and performance prediction of a turbocharged diesel engine with six-cylinder direct injection. To predict the engine performances, we developed a computer program for simulating the operation of a turbocharged diesel engine, and used the commercial GT-Power software to validate the simulation results. The range of variation of the rotational speed of the diesel engine chosen extends from 800 rpm to 2100 rpm. In this paper, we studied the influence of several engine parameters on the brake power and effective efficiency. Moreover, it puts in evidence the existence of two optimal points in the engine, one relative to maximum power and another to maximum efficiency; it was found that if the injection time is advanced, then the maximum levels of pressure and temperature in the cylinder are high.
