Ramesh Assistant Professor, Mechanical Engineering, Veltech Dr RR & Dr SR University, Avadi, Chennai, India ABSTRACT In general only 40% of power produced in the engine is converted into useful work other than that 30% of heat escape through exhaust and 30% of heat is which cannot be converted into useful work is removed as waste heat with the help of cooling system. To convert this waste heat into useful work the cylinder liners and piston head is coated with ceramic coating. This will lead to reduction in heat transfer through the engine, involving an increased efficiency. Change in combustion process due to insulation also affects emissions. Higher gas temperature should reduce the concentration of incomplete combustion products at the expense of an increase in nitrogen oxides (NOx). However a decrease in carbon monoxide (CO) unburned hydrocarbons (HC) is observed. Here we are going to analyze the uncoated cylinder with coated one using ANSYS and in experimental method using thermal image camera. The result depicted that the ceramic coated cylinder is more efficient than uncoated one. Key words: Zirconium Oxide, Thermal Imaging Camera, Cylinder Liner, Piston Head. Cite this Article: M.
