Original Abstract Submitted

the internal combustion engine includes a first oil jet that injects oil toward an inflow hole for flowing oil into the cavity, and a second oil jet that injects oil to a back surface so that the oil does not flow into the cavity. the control device of the internal combustion engine determines whether the temperature of the piston is equal to or higher than a specified temperature which is a threshold value for determining whether the piston has overheated to the extent that cooling is required. when the temperature of the piston is equal to or higher than the specified temperature, the control device cools the piston by using the first oil jet. when the temperature of the piston is lower than the specified temperature, the control device restricts the injection of the oil from the first oil jet and warms up the oil using the second oil jet.
