Abstract—The in-cylinder air motion in internal combustion engines is one of the most important factors controlling the combustion process. It governs the fuel-air mixing and burning rates in diesel engines. In this present work the experimental investigation of air swirl in the cylinder upon the performance and emission of a single cylinder diesel direct injection is presented. This intensification of the swirl is done by the cutting grooves on the crown of the piston, by three different configurations of RGP 6, RGP 9 and normal pistons are investigating performance and emission characteristics. Experiments are carried out on a diesel engine using Modified different configuration piston which is a four stroke single cylinder air cooled and constant speed engine. Performance parameters such as brake power, specific fuel consumption and Thermal efficiency are calculated based on experimental analysis of the engine. Emissions such as carbon monoxide, carbon dioxide and unburnt hydrocarbons are measured.
