Title: Design and development of a software module for analysis of three-dimensional piston ring wear

Abstract:

Increasing oil prices and more stringent emission laws require an improved efficiency from future automotive engines. Additionally, the competition of the automotive market demands longer service intervals and engine lifetimes.

A potential to decrease the specific fuel consumption and improve specific volume is offered by means of increasing engine speed and maximum cylinder pressure. Hence, the mechanical stress on the tribological system including the piston, piston rings, cylinder liner, are increased and the reliability decreases.

The objective of this research is the development of a mathematical model implemented in software, which can deliver a prediction of piston ring wear in internal combustion engines.

The program has been applied to a top compression piston ring of a turbocharged diesel engine at WOT operation conditions.
