Abstract: Motor execution improvement and fumes discharges decrease are two most significant issues to build up an increasingly productive motor with less natural effect. For diesel motor, cylinder geometry is one of the real parameter that influences the motor performance and emissions. In this present research work, engine performance improvement and exhaust emission characteristics reduction was reducing with the help of some modification in piston geometry by using 3 different types of piston geometries. Horizontal, Toroidal and Re-entered pistons. These can be tested on single cylinder water cooled ci motor. Varying Different type’s pistons were analyzed and emissions HC, CO, CO2, O2 and NOx were studied with 5-gas exhaust gas analyzer. The toroidal cylinder gives the best performance and lower emissions at all load conditions.
