Experimental Study on Yttria Stabilized and Titanium Oxide Thermal Barrier Coated Piston Effect on Engine Performance and Emission Characteristics

Most of the energy was being lost through cooling system and exhaust gas, to utilize that convert it a useful job thermal barrier coatings is widely used. Tests were conducted on four stroke, single cylinder diesel engine for which its piston crown coated with thickness 100/100 microns YSZ/TiO2 over 100 NiCr bond coat plasma spray coating technology then results compared uncoated piston. Thermal used better performance, emission combustion characteristics. The tests performed at different load conditions using both pistons results. At maximum there rise in BTE reduction BSFC, CO, HC emissions load. With use NOx increased smoke opacity decreased Finally, convey more efficient than
