A new numerical analysis for piston skirt–liner system lubrication considering the effects of connecting rod inertia

A new numerical analysis for the piston skirt is conducted to consider the effects of the connecting rod inertia on the piston skirt–liner system lubrication. The piston dynamics, the oil film and the friction loss of the system are analyzed and compared with one earlier model that has been adopted widely. The results on a gasoline engine show that the connecting rod inertia does have some influence on the system lubrication as well as the piston dynamics, especially when engine runs at high speeds.
