Thermal Barrier Coating (TBC) on diesel engine performance was studied with a purpose of improving the thermal efficiency by decreasing Specific fuel consumption (SFC) and reducing exhaust emissions. This review paper gives a comparison of a standard diesel engine over a Low heat rejection engine. The experimental results from the various researchers show a gradual improvement in efficiency and specific fuel consumption rate. Higher operating temperature in combustion chamber gives higher efficiency which by using temperature resistant materials. Yttria-stabilized zirconia (YSZ) ceramic, ZrO 2 , Al 2 O 3 , Aluminium titanium are the coatings used on piston crown, cylinder liners, valves by adopting plasma spray technique. The results of LHR engine shows that, NO x emission is increased, whereas the efficiency and SFC are closer to standard engines at Low loads and noticeable improvements are seen at higher loads.
