Variable valve system of internal combustion engine and control method thereof |
摘要 |
A valve characteristic changing mechanism is supplied with oil discharged from an electric oil pump in addition to oil discharged from a mechanical oil pump that is driven by an operation of an internal combustion engine. Driving of the electric oil pump is controlled such that a work rate of the electric oil pump increases as a temperature of the oil supplied to the valve characteristic changing mechanism increases, or as a viscosity of the oil is reduced.
