Less wear on the piston skirts of internal combustion engines

Cover Page

Abstract


A significant proportion of mechanical losses in internal combustion engines accounted for mechanical losses in the cylinder-piston group. Depending on the operating modes of the internal combustion engine, contact interaction in the piston-cylinder pair is possible, which leads to wear of the working surfaces of the resource-determining elements and a decrease in the operational life of the power unit as a whole, in connection with which the reduction of friction losses in the internal combustion engine elements and the piston - cylinder liner coupling in particular is relevant. Both domestic and foreign researchers are engaged in the solution of the above described problems, various profiles of pistons, methods of calculating the parameters of the oil layer are proposed, but the practical state of the issue determines the relevance of research in this direction. The paper considers the possibility of reducing the wear of piston skirts by reducing the contact surface in conjugation and providing an oil film in the friction zone, regardless of engine operating conditions. This opportunity is realized by forming a certain macro profile on the working surface of the piston skirt. The formation of the macrorelief was carried out by means of surface plastic deformation, with the reciprocating movement of a spherical tool on the machined surface.
