  • 摘要:This paper presents a mathematical model of piston-rings-cylinder sealing (TPC) of a combustion engine.The developed model is an itegrated model of gas flow through gaps in TPC unit,displacements and twisting motions of piston rings in ring grooves as well as generation of oil film between ring face surfaces and cylinder liner.Thermal deformations and wear of TPC unit elements as well as heat exchange between flowing gas and surrounding walls,were taken into account in the model.The paper contains descriptions of: assumptions used for developing the model,the model itself,its numerical solution as well as its computer application for carrying out simulation tests.
