This is the review and case studies of the effect of the piston bowl geometry, fuel injection pressure and exhaust gas recirculation on the performance and emissions of the diesel engine. Our attempt is to bring clarity to the understanding of the effects caused by the above mentioned parameters on the diesel engine. This paper discusses how the performance and emission changes occur due to change in injection pressure. Also, what is the effect of piston geometries such as tangentially grooved piston, square bowl piston on the engine due to the turbulence caused by the geometries. This paper also discusses the effect of the change in percentages of the EGR (exhaust gas re-circulation) on the emission and performance of an engine.
