    Abstract: The CFD software STAR-CD developed by CDAJ is adopted to simulate the combustion process of a CNG engine.The simulated cylinder pressure agrees with the experimental data.With numerical simulation,some important information in the cylinder which could not be acquired in the experiment was obtained,such as the velocity and temperature fields.The information from numerical simulation gives some theory guidance for combustion chamber design and optimizing combustion performance.
