摘要:
The use of multigrade oil in engine lubrication is being advocated to consumers to minimize viscosity-temperature effect. However, its effect on piston ring-liner contact has not been fully ascertained. In this work, an attempt has been made to evaluate the friction behavior of multigrade oil in piston ring lubrication. The theoretical model developed by the authors predicts thinner oil films as a result of introduction of multigrade oil in the hydrodynamic zone and a larger piston travel distance near the TDC region in the compression-power stroke cycle without any appreciable film thickness. The multigrade oils are known to offer elasticity, and this is also considered in the analysis to evaluate film thickness.
