A Numerical Analysis on the Effect of Several Factors on the Oil Pressure under Oil Control Ring Which Relates to Oil Consumption

Abstract

Importance of the reduction of oil consumption in developing the internal combustion engine is increasing for the protection of global environment. Oil pressure under the oil control ring could affect the oil consumption, so estimation of the oil pressure is required in order to analyze mechanism of oil rising through the piston ring. In this study, the factors of oil pressure generation are investigated by the numerical analysis model, and also knowledge of piston design for the purpose of reducing the oil consumption is shown.
