Abstract
An ECU for an internal combustion engine predicts change in the driving state of the engine when switching from port injection mode to in-cylinder injection mode. In accordance with the prediction, the ECU actuates a high-pressure pump before entering the in-cylinder injection mode to pressurize the fuel supplied to an air-intake passage injector.
