The Effect of Intake Port Shape on Gasoline Engine Combustion in Cylinder

摘要

The effect of intake port shape on gasoline engine combustion performance was studied by CFD technology. The correlation of CFD simulation and experiment data is good, the all results shows the combustion performance of intake port with high tumble is better than that of intake port with low tumble, the high tumble in cylinder transfers into turbulence kinetic energy as the piston close to top dead center during compression stoke, it is good for accelerating the process of combustion in cylinder and improving the performance of combustion.
