  • Patent number: 10519824
    Abstract: Disclosed herein is an oil supply device for an internal combustion engine, which includes a control unit that controls activation of an electric oil pump and that functions as either a reserve oil level estimator for estimating the level of oil reserved in auxiliary chambers or a reserve oil level detector for detecting the level of the oil reserved there. When it is estimated or detected that the level of the oil reserved in the auxiliary chambers has become equal to or less than a predetermined reserve oil level while the internal combustion engine is OFF, the control unit performs an oil replenishment control to replenish the auxiliary chambers with the oil by activating the electric oil pump.
