Abstract
An engine oil supply apparatus includes: an oil pump; an oil supply path which supplies oil to a hydraulic operating section of an engine; an oil cooler which is provided on the oil supply path and which cools oil discharged from the oil pump; and a control apparatus which sets a required oil pressure required from the hydraulic operating section in accordance with an operation state of the engine, as a target oil pressure, and controls the discharge amount of the oil pump so that an oil pressure inside the oil supply path equals the target oil pressure. The control apparatus controls the oil pump so that, during an operation state of the engine where the oil enters a prescribed high oil temperature state, the oil is discharged in an amount exceeding a discharge amount corresponding to the required oil pressure of the hydraulic operating section.
