Swirl Induction with Dimpled Cylinder Head and its Effect on Exhaust Emission of Diesel Engine

Pankaj N.Shrirao, Kapil B.Salve, Sachin S. Pente

This paper aims at studying the effect of in-cylinder air turbulence generated by oval shape dimpled cylinder head on engine performance as well as on its exhaust emissions. In view this, experimental investigation has been carried out to find the effect of swirl on the performance characteristics of the engine as well as on its exhaust emissions, by inducing swirl in cylinder with different configurations of cylinder head i.e. in the order of number of oval shape dimples 1& 3. This intensification of the swirl is done by making in order to enhance performance characteristics of the engine. It is inferred that, engine with dimpled cylinder head optimized the performance of engine and yields less exhaust emission as compared to the engine with conventional cylinder head. This is because dimpled cylinder head achieved a higher swirl coefficient and swirl ratio as compared with conventional cylinder head. The increase in swirl intensity by dimpled cylinder head resulted in better mixing of air- fuel mixture which improves the combustion rate resulted in reduction of exhaust emissions.
