ANALYSIS OF HEAT STRESSES OF THE PARTS OF THE CYLINDER-PISTON GROUP WITH HEAT-PROTECTIVE COATINGS IN AN INTERNAL-COMBUSTION ENGINE

摘要

The process of heat exchange in 'the cylinder of an internal-combustion engine has been investigated and the heat stresses of the working surfaces of the piston and the cylinder head have been analyzed. A method for calculating the heat resistance, the strength, and the thickness of heat-protective coatings has been developed. Results of thermal-cycle testing of a piston with heat-resistant coatings, the properties of which were calculated by the method proposed, are presented.
