A Review on Thermal Barrier Coatings (TBC) Usage and Effect on Internal Combustion Engine

Abstract

A growing number of vehicles polluting the environment and are also responsible for the fossil fuel depletion. To overcome these problems, the efficiency of an internal combustion engine needs to be increased. Many types of research have been carried out on decreasing the polluting gases from the engine by treating them with chemicals or by trapping them with some means. But some advanced methods are also dominating the automobile industry to overcome such problems. The use of thermal barrier coating (TBC) on the surface of the components of engine (piston crown, cylinder head, and combustion chamber) is one of the advanced technologies to increase the engine power and efficiency which means decrement in the harmful exhaust gases from the engine. This technology is the advancement in the material of the components of the diesel IC engine by coating it with the layer of ceramic material and making it more insulating to trap the heat within the chamber. As the operating temperature of the engine increases, it is in turn helpful in burning the maximum fuel and hence decreasing the ratio of particulate matter, smog, and other harmful gases. This will result in less pollution and better engine efficiency. The objective of this paper is to present a review report on the usage of the thermal barrier coating on the engine components like piston crown, cylinder head, combustion chamber, and effect of the thermal barrier coating in the internal combustion engine parameters.
