Abstract
A fuel injection control device sets an injection sharing ratio of a quantity of a fuel injected in an intake stroke, and a quantity of a fuel injected in a compression stroke, based on an operating state or an environmental condition of the engine, and manipulates the cylinder fuel injection device so as to inject a part or all of a required fuel in the intake stroke and inject a remaining part in the compression stroke, in accordance with the set injection sharing ratio. The injection sharing ratio is set so as to make a proportion of the quantity of the fuel which is injected in the intake stroke larger when a temperature of air which is taken into a cylinder is higher than a fuel which is injected from the cylinder fuel injection device, as compared to when the temperature of the air is lower than the fuel.
