Abstract
An engine lubrication system including: an oil pump configured to be driven by an engine; an oil jet mechanism configured to inject oil pressure-fed by the oil pump to a piston; and circuitry configured to set a target hydraulic pressure of the oil injected from the oil jet mechanism according to an operation state of the engine; determine a hydraulic pressure state of the oil injected from the oil jet mechanism; and change a gear stage of the automatic transmission to a lower gear stage in a case that a predetermined condition between the determined hydraulic pressure state and the target hydraulic pressure is satisfied.
