In this investigation, the Internal combustion engine is established because of the main power supply to the automobile is internal combustion engine. For this reason, heaps analysis goes on combustion to extend the performance and reduce the emissions. So as to fulfill the tight emission standards, vital efforts are created for the event of isolated I.C engines. During this project work done on the combustion chamber. The new design and modification of the piston bowl is projected to cut back the emissions and improve the engine performance with the assistance of RAMTIL OIL and DIESEL fuels. The circular stepped dish type combustion chamber is to produce higher mixture of fuel with intake air so higher mixture of fuel can result sensible combustion of mixture. This design of the piston could improve the squish of the air fuel mixture, which can end up in higher thermal efficiency and emission reduction of exhaust emissions. It’s projected to hold out associate experiment on a four-stroke single cylinder DI Diesel engine by victimization of DIESEL and RAMTIL oil fuel (i.e., within the type of blends B5, B10, B15, B20, B25) as another fuel. Performance parameters like brake thermal efficiency, specific fuel consumption, and overall efficiencies are to be calculated. The Brake Thermal efficiency of the engine is increased compared to diesel fuel with normal piston to the modified (circular dish type combustion chamber) piston with RAMTIL oil blends. The Brake Thermal efficiency (30.77%) of the engine is greatly improved with the comparison of basic piston to changed piston with B15 fuel. The Nox emissions of the B10 and B15 are decreased (min 181 ppm) at full load conditions.
