Abstract
Piston ring pack performance is very critical to diesel engine blow-by and oil consumption. As structural analysis tools such as Finite Element Analysis and Boundary Element Analysis can be used to ensure the piston structural integrity, cylinder kit dynamics models are being used to predict power cylinder system performance. In this paper, detail comparisons of engine test measurements and model predictions under various operating conditions and with different ring pack configurations are presented. The cylinder kit model used for this paper is one out of six different models that were evaluated.
