Internal combustion engines have been used as stationary engines in factories and power plants for a long time. In recent years, the demand for the environmental protection and the use of alternative fuels has excited the product market to power generation systems using heavy duty gas engines. This research activity investigates the effect of the piston bowl depth on the performance and emissions of gas engines. Towards this purpose, the 3D computational fluid dynamic model was used to simulate the cycle engine. By implementing equations (of the combustion, the turbulence and the pollution), the close cycle of the engine was simulated and results were presented in graphs and contours. Firstly, results were validated with experimental data and by simulating of three different pistons, their pressures and temperatures, inside the cylinder and their amounts of emissions were compared. Obtained results showed that the combustion chamber, which was created best mixing and the optimum turbulence, had the best performance and released lower emissions.
