In this study, for the first time, a nano ceramic material of Al 2 O 3 was used as thermal barrier coating in a diesel engine. In the first phase, engine combustion chamber elements (cylinder head, cylinder liner, valves, and piston crown face) were coated with 200 lm thickness nano ceramic material of Al 2 O 3 by using plasma spray-coating method. In second phase, experiments were carried out on Al 2 O 3 -coated engine by using Pongamia methyl ester (PME), PME blends of 20 and 40% by volume with diesel and pure diesel. The test run was repeated on uncoated engine and the results were compared. An increase in engine power and decrease in specific fuel consumption, as well as significant improvements in exhaust gas emissions (except NO x ) and smoke density, were observed for all test fuels used in the Al 2 O 3 -coated engine compared with that of the uncoated engine.

“…The energy input or consumption to the engine in case of coated engine is less compared to uncoated engine which results in increase in efficiency at all loads. Thermal barrier coating offered higher efficiency by 5e9% with diesel operation compared to the standard engine [3] and [16]. Various studies [8e11] on biodiesel such as canola, cotton, corn and sunflower methyl ester in LHR engine proved an improvement in thermal efficiency between 3.5 and 8% and while in this study it is 6.8% for RME-20, 4.9% for PME-20 and 3.4% for pure diesel.…”

Internal combustion engines have been widely used for past 100 years. In the development of engine components a number of special techniques are used to compact the hostile operating environment, which usually includes high and cyclic forces, high and cyclic temperatures, sliding and often corrosion and/or erosion. In this study, 3‐D finite element structural and thermal analyses were carried out on both uncoated (without coating) and ceramic‐coated engine piston. A 150 µm super alloy bond coating (NiCrAlY) was first applied to the piston. Then, piston was covered by 350 µm thickness of MgZrO3 as top coating. The analysis can be utilized to detect possible thermal problem spots in an engine, and to provide input data for general engine modeling and engine lubrication and wear studies.
