Theoretical Prerequisites for Lowering Piston Temperature in Internal Combustion Engines

One of the ways to improve the reliability and service life of the cylinder-piston group of an internal combustion engine is to use heat insulation and improve the rejection of heat from combustion chamber parts. The most efficient existing method consists in application of thermal insulation coatings on the work surfaces of the piston, in particular, the formation of an oxidized layer on the piston crown. In order to find out how efficient the suggested method is, the authors have carried out theoretical calculations and comparative laboratory studies of standard and oxidized pistons. It has been found out that the formation of an oxidized layer on the work surfaces of the piston crown allows lowering of the inner surface temperature of the piston by 23.6% on average as compared to typical pistons.
