INFLUENCE OF THERMAL BARRIER COATING IN S.I ENGINE

Energy is very important for existence of life, welfare level and social development of people as well as economic growth. Energy demand around the world is increasing rapidly as a result of ongoing trends in modernization and industrialization. The rapid increase in fuel expenses, the decreasing supply of high-grade fuel on the market and environment necessitates stimulated research on efficient engine with acceptable emission characteristics. The state-of-art thermal barrier coating (TBC) provides the potential for higher thermal efficiency of the engine, with improved combustion and reduced emission. One advantage of TBC is that ceramic is better than the conventional materials. MgZrO3, CaZrO3 and AlO3 ¿ZrO2 are some of the ceramic materials used as TBC. A two-stroke single cylinder petrol engine is selected for carrying out the experiment. It is planned to use the TBC on the piston head and study the emission and performance characteristics of the engine with and without TBC under various loading condition.
