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.
摘要（中）：

除了从由内燃机的动作驱动的机械油泵排出的油以外，向电动油泵供给除油的阀特性变更机构。 控制电动油泵的驱动，使得电动油泵的工作速度随着供应给阀特性变化机构的油的温度升高或随着油的粘度降低而增加。
