Abstract
An internal combustion engine control device for a dual-injection internal combustion engine acquires first and second increase values, which are fuel increase ratios according to respective alcohol concentrations of a fuel injected by cylinder injection and a fuel injected by port injection. The control device determines a basic total injection amount of fuel that should be supplied to each cylinder in the case where the alcohol concentration of the fuel is zero. An amount of fuel injected from a cylinder injection valve is determined as if the alcohol concentration of the fuel were zero. A total injection amount is to correspond to an amount in accordance with the basic total injection amount and both, the first increase value and the second increase value, so that the increase in injected fuel amount is borne by port injection.
