Application of Energy Efficient Thermal Barrier Coatings for Internal Combustion Engines

I. C. engines used in transportation, energy, and defense sectors rely on high-temperature thermal-barrier coatings for improved efficiencies and power. Higher demands implementing stricter regulations on emission measure, high fuel prices, more precise requirements in the field of the vehicle emissions increasing the pressure on the engine manufacturers to utilise technologies which contribute to a reduction in air pollution, including limits on nitrogen oxides, particulate matter, greenhouse gases and require internal combustion engines to be optimized with respect to their frictional losses and wear. Meeting these standards can require complex and costly upgrades to diesel engines. In this article, Literature survey carried out on the basis of reference books, conference volume and Research paper. The details about Thermal Barrier coating, coating methods and researcher results and their conclusions are discussed in depth with facts and figure based on presented articles. The Thermal Barrier coating method has wide effects on the brake specific fuel consumption, brake power and the Emission characteristic, pollution contents and the Thermal fatigue lifetime of engine components. By using Air plasma thermal spray method there are several benefits by applying ceramic layers on the combustion chamber, including the piston, the cylinder head, the cylinder block, and intake and exhaust valves.
