Abstract: The most recent developments in Thermal Barrier Coating (TBC) relate to engine performance, manufacturing and other related challenges. TBC on the piston crown and valves to enhance engine characteristics while using diesel and Mahua Methyl Ester (MME) as a petroleum fuel has a great sustainable development. For this utility, a Direct Injection (DI) conventional diesel engine was renewed to an LHR engine by applying 0.5 mm thickness of 3Al 2 O 3 -2SiO 2 (as TBC) onto the piston crown and valves. The MME is used in the LHR (Low Heat Rejection) engine. For examination, the fuel injector pressure is set at 200 bar. Compared to a standard DI diesel engine, the results demonstrate that the application of TBC boosts brake thermal efficiency to 13.65% at 25% load. The LHR engine’s SFC and BTE significantly improved at full load while using MME fuel. The lower temperature of exhaust gases is achieved by combining MME and diesel fuels with TBC. It was observed that both MME with and without TBC significantly reduced the smoke density. In addition, it was exposed that using MME fuel with TBC very slightly reduced carbon monoxide emissions under all loads. It was also shown that MME with TBC significantly reduced environmental hydrocarbon emissions at all loads.
