Abstract
A piston skirt contact analysis was conducted using a piston skirt lubrication model that takes into account the actual skirt profile, elastic deformation of the piston skirt, bore deformation and boundary lubrication. This study also examined the correlation between the calculated piston skirt wear and experimental wear data. It was found that there is good correlation between the level of skirt wear and ΣPV, representing the product of the oil-film pressure and piston speed. The results indicate that a prediction of skirt contact can be an effective design tool.
