Claim Text:
1. A fuel injection control device for an internal combustion engine having a cylinder fuel injection device, comprising: injection sharing ratio setting means that sets an injection sharing ratio of a quantity of a fuel which is injected in an intake stroke, and a quantity of a fuel which is injected in a compression stroke, in accordance with an operating state or an environmental condition of the internal combustion engine; and manipulating means that manipulates the cylinder fuel injection device 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, wherein the injection sharing ratio setting means sets the injection sharing ratio 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 determined to be higher than a temperature of a fuel which is injected from the cylinder fuel injection device, as compared with a case where the temperature of the air which is taken into the cylinder is determined to be lower than the temperature of the fuel which is injected from the cylinder fuel injection device.
