Internal combustion engines are inherently ineffecient. Our project will focus on cylinder head turbulence and cylinder head flow to improve performance. From this research, optimum in cylinder turbulence can be determined. This information can be used to demonstrate how this turbulence can be used to increase efficiency.

Current Progress:

In our research have implemented the physics model of turbulence. The model is also known at the K-Epsilon model. Implementing this is vital for continuation. THe mathematical model that we have been utilizing pertains to turbulence in an open atmosphere, not a closed atmosphere like that of a internal combustion engine.

Expected Results

By modifying the K-Epsilon Model, we can determine methods of improving cylinder head flow. ALterations in cyliner head design will be made to imrpove combustion efficiency. We expect to see .1 to .5 percent improvement of combustion efficiency
