Abstract
A control apparatus controls the opening and closing timings of the intake and exhaust valves and the fuel injection timing. When the water temperature of the engine is equal to or below a predetermined value, the exhaust valve closes before the top dead center, and the intake valve opens after the top dead center. At the same time, if the pressure inside the intake passage is equal to or below a predetermined value, the fuel injection is conducted during the intake process. Furthermore, the intake fuel injection timing is changed according to the rotational speed of the engine. In this manner, the vaporization of the injected fuel is promoted, and stability of the combustion is improved. Also the exhaust emission is improved, while the fuel consumption is reduced.
