Abstract: Demand for Fossil fuels has been increasing tremendously which cause environmental threat. For this reason a numerous studies are ongoing for renewable sources of energy worldwide. This paper investigates the effect of using TBC to diminish emissions from engine exhaust specifically nitrogen oxide and to augment the performance of the engine. Engine Components were coated with Mg-PSZ of which 150µm thinness of Zro2-24Mgo over a 50µm thickness of NiCrAlY bond. The input parameters considered for this study includes engine speed, compression ratio, stroke length and Neli oil. The output parameters such as thermal efficiency, Brake power, Brake Specific Fuel Consumption, Volumetric Efficiency and Emissions of NOx, CO, HC were studied in a thermal barrier coated engine running with Neli oil and diesel fuel blend. From this experiment it is observed that there is a significant improvement in the results of engine performance and emission characteristics
