Abstract: This paper explains the importance of applying thermal barrier coating (TBC) technique in internal combustion engines by providing an effective way of reducing gas emission which are carbon monoxide (CO), oxide of nitrogen (NOX), hydrocarbon (HC) including particulate matter (PM) thereby increasing engine performance (brake thermal efficiency) achieved by applying coating layers on some internal combustion engine parts using materials with low thermal conductivities and matched coefficients of thermal expansion (CTE close to the substrate material) which are mainly ceramics. Energy demand for various activities of life is increasing on a daily basis. The world depends majorly on non-renewable energy sources from fossil fuels to meet these energy demands. To be comfortable in life, better means of transportation and provision of power are required. Compression and spark ignition engines which are also called Internal Combustion Engines (ICEs) provide better transport facilities and power. However, combusting these fuels in automobile and stationary engines produces unfriendly atmosphere, contaminates water and air that are consumed by man. Pollution created as a result of combustion of gases in ICE is one of the worst man made contribution to atmospheric pollution.
