ABSTRACT:
A reference injection quantity of fuel to be injected from a port injection valve and an in-cylinder injection valve as well as an injection ratio are determined based on an operation condition. A ratio between a feedback correction amount for port injection and a feedback correction amount for in-cylinder injection is set equal to a ratio of the reference injection quantity. If an injection quantity obtained as a result of addition of a correction amount is smaller than a minimum injection quantity of the injection valve, feedback correction is prohibited. Meanwhile, if the feedback correction amount is small, only the injection valve attaining a larger injection quantity is subjected to feedback correction.
