In this paper, the compression process for a certain type of internal combustion engine is simulated in the transient by using the fluent software. In the process of the numerical simulation, we check the computing grid model of internal combustion engine, and illustrates the rationality. The distribution situation and change tendency of pressure field and the turbulent kinetic energy with different crank shaft Angle under different speed are studied.
