Original Abstract
Piston rings play an important role in the lubricant characteristic of reciprocating engines with the consequences on engine wear, power losses and a vast amount of lubricating oil consumption. The computational solution of piston ring dynamics is a very complex problem and it requires multiple numerical approaches supplemented by suitable inputs. The paper demonstrates the principles of the numerical solution of piston ring dynamics in mixed lubrication conditions incorporating a virtual engine and experimental inputs. The simulation algorithm is incorporated into user guided interface and it is available for industry usages. The solution results are presented on a diesel turbocharged engine with three piston ring configuration.
