Influence of Turbulence Generated Air Swirl on Performance and Emission of SI Engine
Mr. Smit K.Mistry,  Mrs.Vandana Y. Gajjar
Turbulence can he pictured as a random motion in three dimensions with vortices of varying size superimposed on one another, and randomly distributed within the flow. An experimental investigation was carried out to understand the effects on performance and exhaust emissions. For this research work, A Honda single cylinder, 4 stroke, air-cooled, having 2 Brake Horse Power, naturally aspired engine was used. Swirling Device was fitted in intake system of engine. Two Intake system configurations were experimentally checked. The emissions, volumetric efficiency and brake thermal efficiency were also compared by using Swirling Device, with existing intake system. The specific fuel consumption (SFC), volumetric efficiency and exhaust gas emission decreased, whereas brake thermal efficiency (BTE) increase within the test. All experiments were conducted at different load conditions using an electric alternator generator and the exhaust analysis was carried out with the help of multi gas exhaust emission meter. Swirling Device in Existing intake System shows decrease in exhaust emission and fuel consumptions at different load conditions
