Abstract

The aim of this project is to achieve helical threads in the inlet manifold with optimum pitch obtained by CFD Analysis for direct injection (DI) single cylinder diesel engine in order to create the turbulence by air swirl. Achieving this with different pitch of inlet manifold by experimental methods would cost time and money. A good air swirl promotes the fast combustion and improves the efficiency. Therefore to produce high turbulence prior to combustion within the cylinder, swirl induced by the inlet manifold will be helpful. The measurements are done at constant speed of 1500 rpm. This project aims at studying the effect of air swirl generated by directing the air flow in intake manifold on engine performance as well as on its exhaust emissions. In view this, Numerical and Experimental investigation has been carried out to find the effect of air swirl on the performance characteristics of the engine as well as on its exhaust emissions with normal manifold and helical threaded manifold were calculated and compared.
