Effect of Induction Swirl and Piston Configuration in a Constant Speed Four Stroke Diesel Engine

Abstract

New strategies and optimization in present techniques are introduced in increasing the demands of consumption of fuel in I.C engines. Movement of air within the combustion chamber effects the formation of air and fuel mixture with fine spraying of fuel. Complete combustion and reduction in knocking will be obtained by better mixing of air and fuel. For this purpose C.I with four stroke, working power 5KW and with the speed 1500rpm is used to analyze the engine characteristics. For betterment of the engine, air swirl motion technology is used as the optimized parameter. A nozzle of convergent divergent, inlet valves, exhaust valves, piston modification are incorporated for increasing the velocity of air and for better mixing of air – fuel mixture for better combustion.  This may leads to increase in velocity and generates the turbulence at the outlet of the inlet manifold which leads to the better combustion.  By making the above modifications in three methods, the characteristics performance of the engine and the emission parameters are evaluated.
