The thermal efficiency of commercially used engine ranges from 38% to 42%, as nearly 58% to 62 % of energy is lost of heat. Nearly 30% is retained in exhaust gas and the remaining is removed in cooling water/air, in order to save that energy the hot parts are insulated TBC.TBC is that ceramic is better than the conventional materials. CaZrO3, Mullite and Al2O3 –ZrO2 are some of the ceramic materials used as TBC. A four stroke single cylinder Kirloskar diesel engine is selected for carrying out of the experiment. It is planned to use the TBC (Mullite + aluminum titanate) on the piston head by plasma spray process for the performance characteristics of the engine with and without TBC under various loading condition. The purpose of using these materials is to reduce the heat loss from engine. As the experimental investigation results of significant reduction in specific fuel consumption as 1.4% and effective improvement in brake thermal efficiency as 1.1%.
