Abstract:
An engine control apparatus is configured to control a direct injection engine that includes a combustion chamber and an intake system including an intake port. The engine control apparatus includes a cleaning component sensor and a mode controller. The cleaning component sensor is provided in a fuel system and configured to detect a cleaning component included in fuel. The fuel system includes a fuel tank and an injector and is configured to supply the fuel to the combustion chamber. The mode controller is configured to cause execution of a cleaning mode by the direct injection engine, under a state in which the cleaning component included in the fuel is higher than a threshold. The cleaning mode includes increasing an amount of a fuel-air mixture flowing back from the combustion chamber to the intake port.

Claim (Index 3):
The engine control apparatus according to  claim 1 , wherein\n the intake system further includes an intake valve configured to cause the intake port to be open or closed, and the mode controller causes the execution of the cleaning mode by postponing close timing of the intake valve.
