るエンジンの潤滑装置。[Claims for Utility Model Registration] (1) Equipped with a supercharger and a metering oil pump, oil is supplied from the metering oil pump to the engine through an oil supply port that opens at a portion where intake negative pressure acts. This is an engine lubricating system that supplies air to the oil supply port from the intake passage downstream of the supercharger, and the amount of oil discharged by the metering oil pump is increased in the supercharged region. Characteristic engine lubrication system. (2) In the engine lubricating device according to claim 1, the oil discharge amount of the metering oil pump is feedback-controlled so as to follow a target value set according to the operating state of the engine, while Immediately after the state shifts to the supercharging region, if the oil discharge amount is higher than the target value, an oil discharge amount control means is provided that temporarily stops deviation correction in the direction of decreasing the oil discharge amount. lubricating system for the engine.
