abstract

An important portion of the total power loss in a modem automotive engine is due to piston ring/cylinder bore friction. This paper introduces the results of simulations about the interaction of a SI engine piston ring taking into account the mixed lubrication regime, the ring flexibility in presence of piston approaching motion to the cylinder liner. The friction force calculations show a visible difference between the ring portion interacting with the two cylinder sides (Thrust and Anti-Thrust) due to specific oil film wedges caused by flexibility and piston lateral motion. The effects of engine speed, radial tension, surface roughness and ring shape are also investigable.
