Abstract
A combustion chamber of an engine has a fuel injector provided for injecting fuel directly in the combustion chamber. A fuel injector and a gap of a spark plug are located on the axis of the cylinder of the engine. A fuel injection finishing crank angle is set at an angle to advance an ignition timing in accordance with an arrival time of a fuel spray at the tap, and a fuel injection starting angle with respect to the fuel injection finishing angle is set in accordance with a quantity of the injected fuel.
