The influence of inter-ring pressures on piston-ring/liner tribological conjunction
journal contribution
posted on 2013-02-08, 11:05 authored by W.W.F. Chong, S.J. Howell-Smith, M. Teodorescu, M.D. VaughanThe article proposes a mathematical model, which predicts the frictional performance of an internal combustion engine compression ring in the vicinity of the top dead center region. It accounts for the blow-by induced inter-ring pressures drop and for the cavitation region at the trailing edge of the contact. The model is used to predict the behaviour of both new and worn compression rings for wide open throttle operating conditions. It is shown that the wear of the ring profile increases the oil film thickness decrease the frictional losses and significantly reduces the extent of the cavitation region.
