This work focuses on thermal barrier coating (TBC) for a thickness of 300µm insulated in combustion chamber for single cylinder four stroke diesel engine. The piston crown and inlet and exhaust value head are coated by using Air plasma spray coating technique. The ceramic powder material is molybdenum (Mo) and Aluminum Oxide Titanium Dioxide (Al2O3-TiO2). The coating on single cylinder four stroke diesel engine aims at reducing the emission behaviors to attain a greener and cleaner system. The engine performance test with the coating on the combustion chamber was carried out to investigate brake power, brake thermal efficiency, volumetric efficiency, brake specific fuel consumption and air fuel ratio. Also emission characteristic test are carried out to investigate unburned hydrocarbon (HC), carbon monoxide (CO), oxide of nitrogen (NO, NO2, NO3 etc..) NOx and engine emitted smoke opacity. The effect of (Al2O3-TiO2) coated engine combustion chamber and also (Mo) coated engine combustion chamber is analyzed and concluded that the brake thermal efficiency, brake specific fuel consumption shows a significantly increases because of this coating materials. The effect of (Al2O3-TiO2) coating reduces the engine emissions producing HC, CO significantly. This work appreciates the usage of coating materials in the engine combustion chambers to increase the performance characteristics and emission characteristics of the engine.
