Influence of Thermal Barrier Coating and Mems Biodiesel on the Performance And Emission Characteristics of Single Cylinder Diesel Engine

The aim of the investigation is to determine the CI engine performance and emission characteristics of methyl ester mango seed biodiesel fueled and zirconia thermal barrier coated single cylinder four stroke diesel engine. The piston, piston head, inlet, and outlet valves were coated with zirconia thermal barrier coating material. The engine was operated for different injection pressures for B00, B30, TBC+B00 and TBC+B30 biodiesels. The experiments were conducted on water cooled diesel engine to determine the indicated pressure, brake thermal efficiency, specific fuel consumption and emission characteristics. The result indicates that the brake thermal efficiency of the biodiesel was slightly lower than the brake thermal efficiency of diesel fueled engine. The brake thermal efficiency of coated condition is higher than the uncoated condition. The specific fuel consumption of biodiesel was more compared to diesel and specific fuel consumption for coated condition is lower than the uncoated condition. The emission charecteristics were lower for coated condition than the uncoated condition.
