Abstract: Provided is a control device for an internal combustion engine that includes: a water-cooled cooler (intercooler) arranged at at least one of a portion of an intake air passage located on the upstream side of an intake port and an EGR passage; and a water pump configured to supply a cooling water with the cooler. The control device is configured: to execute a water supply operation that supplies the cooling water with the cooler by actuating the water pump when its execution condition which includes a requirement that a cooler temperature is higher than a cooling water temperature is met during stop of the internal combustion engine; and not to execute the water supply operation when the cooler temperature is lower than or equal to the cooling water temperature during stop of the internal combustion engine.

Abstract: The deterioration of combustion due to condensed water flowing into a cylinder is suppressed as much as possible. A control apparatus for an internal combustion engine is applied to an internal combustion engine which includes a fuel injection valve that directly injects fuel into a cylinder and a spark plug. The internal combustion engine is constructed so that the fuel goes to the spark plug. The control apparatus comprising a controller configured to: predict whether condensed water flows into the cylinder during an intake stroke; and carry out first injection control to perform fuel injection in a predetermined period of time within a period of time which is after closure of an exhaust valve and before the condensed water flows into the cylinder, and second injection control to perform fuel injection in a compression stroke before ignition, if an inflow of the condensed water into the cylinder is predicted.
