Abstract
An SI engine gets the charge as a mixture of air and fuel. The quality of the mixture plays a very important factor that decides the quality of combustion, efficiency of the engine, particulate and acoustic emission. Hence it is important to arrive at the right quality of fuel and method of induction of charge. This study focuses on comparison of premixed and partially premixed combustion modes. Various parameters are studied and compared using the Ansys Fluent software. Contours such as progress variable, total pressure, total temperature and turbulent flame speed are obtained at various crank angles for premixed and partially premixed modes. By this simulation it is concluded that partially premixed mode is a better viewpoint in engine design.
