Abstract—The application of TBCs in engines reduces the heat transfer to the engine cooling jacket through the combustion chamber surfaces (which include the cylinder head, liner, and piston crown) and piston rings. This paper deals with the study and comparison of various coatings applied on IC engine pistons and their effects on efficiencies and fuel consumption. It is well known fact that about 30% of the energy supplied is lost through the coolant and the 30% is wasted through friction and other losses, thus leaving only 30% of energy utilization for useful purposes. There have been numerous research papers in recent years describing the theoretical benefits obtained from the use of ceramic components in reciprocating engines, but that describes practical results is very limited. This paper gives the comparison of various practical experiments on coatings in IC engines and their effects. This paper serves as a guide, i.e., collection of all coating effects from the literature for any future development in the IC engine coating industry.
