Abstract: In this study, for the first time, a nanoceramic Al2O3 was used as a coating material in the low heat rejection engine concept. Experiments were conducted on single cylinder, four stroke, water cooled, and direct injection diesel engine. First, the engine was tested at different load conditions without coating. Then, combustion chamber surfaces cylinder head, cylinder liner, valves, and piston crown face were coated with nanoceramic material of Al2O3 using plasma spray method. Comparative evaluation on performance and combustion characteristics using diesel, multi-blend biodiesel and its blends was studied in the ceramic coated and uncoated engines under the same running conditions. An increase in engine power, brake thermal efficiency and a decrease in specific fuel consumption were observed in the ceramic coated engine compared to that of normal engine

Keywords: Multi-blend biodiesel, low heat rejection engine
