Purpose: In this research, Cerium Stabilized Zirconia is coated on the I.C engine cylinder liner using Plasma Spray Coating technique. The coating system has effects on the fuel consumption, the power and the combustion efficiency, pollution contents. Their performance characteristics and results are studied and tabulated. Design/methodology/approach: Thermal Barrier Coating (TBC) are used to achieve the reduced heat rejection in engine cylinders. It is known that the efficiency of internal combustion diesel engines changes 38-42%. It is about 60% of the fuel energy dismissed from combustion chamber. Findings: The results showed that, increasing the brake thermal efficiency and decreasing the specific fuel consumption for the light heat rejection engine with thermal coated cylinder liner compared to that of standard engine. There was increasing the NOx emission and O2 for thermal barrier coated engine. Practical implications: To save energy, combustion chamber component is coated with low thermal conduction materials. In this paper, we are giving idea to thermal barrier coating and ceramic materials which are used for making low heat released engines. It reduces the excessive heat transfer to the coolant and exhaust system, thus improves the mechanical and thermal efficiency
