ABSTRACT:
For an internal combustion engine having an in-cylinder injector and an intake manifold injector, setting of the ratio of fuel injection (DI ratio) between these injectors is changed depending on whether the intake manifold injector is in a high temperature state or a non-high temperature state (normal state). Specifically, when the intake manifold injector is at a high temperature, the setting of the DI ratio is controlled so that the quantity of fuel to be injected from the intake manifold injector is larger than that according to setting of the fuel injection quantity in the normal state under the same engine conditions.
