Abstract
In this investigation, the combustion, performance and emission characteristics of a diesel engine powered with Modified piston (MP) are studied. Engine tests have been carried out using conventional diesel and 20% blend of adelfa biodiesel [A20]. Results obtained from renewable fuel A20 in conventional engine have shown reduction in brake thermal efficiency that may be ascribed to poor air fuel mixing characteristics and higher viscosity of the fuel. This prompted the research towards improvement of turbulence for better air fuel mixing through a novel modification of the piston. The engine with modified piston has shown improved Brake thermal efficiency (BTE), Combustion characteristics and reduced hydrocarbon (HC), carbon mono oxide (CO), and smoke emissions. Nevertheless, the nitrogen oxide emissions have been found to be slightly higher than the conventional unmodified engine.
