Abstract
An engine control device is provided which includes a first fuel injection valve; a second injection valve provided at such a position that the amount of fuel injected by the second fuel injection valve and adhering to the inner peripheral wall of a cylinder is smaller; a cooling water temperature detector for detecting the temperature of cooling water for cooling an engine; and an injection ratio determining arrangement for determining the ratio between the amount of fuel injected by the first fuel injection valve and the amount of fuel injected by the second fuel injection valve based on the temperature of cooling water. The injection ratio determining arrangement stores an injection amount adjustment operation range in which the injection ratio determining arrangement is configured to increase the fuel injection ratio of the amount of fuel injected by the second fuel injection valve, when the temperature of cooling water falls.
