Abstract

Abstract It is considered that the reduction of oil control ring tension is a major problem in reducing the friction-loss of internal combustion engines. The authors have successfully developed a calculating method for the axial behavior prediction of a three piece type oil control ring as a method used in reduction of lube-oil consumption when a lower tension ring is used. By means of this method, the authors found a reduction of lube-oil consumption could be expected by optimizing design parameters of the oil ring, the tension and the seating tab angle of expander-spacer, and the gas pressure on the 3rd land.
