Vaibhav C. Bhatt,  Vandana Y. Gajjar
Extensive research is going on to improve the combustion efficiency of CI Engine. Combustion efficiency of CI Engine can be increased by creating turbulence, by designing intake system, by designing combustion chamber. A good swirl promotes fast combustion to improve the efficiency. So in this present work a study about influence of air swirl in the combustion chamber upon the performance and emission of a diesel engine is presented. In order to achieve different swirl intensity to improve combustibility of combustible mixture in the cylinder, three different configurations of piston i.e. in the order of number of grooves 4, 8 and 12 are used to intensify the swirl for the better mixing of fuel and air and their effect on the performance and emission are recorded.
Keywords- Diesel Engine, Air Swirl, Cylinder, Efficiency and Emission
