PURPOSE:To improve the durability of a fuel injection valve by making the specified injection completion time freely variably settable according to the alcohol density in the fuel in the body variably controlling the injection start time in order to finish the fuel injection at the specified fuel injection completion time. CONSTITUTION:An alcohol sensor A detecting the alcohol density in a fuel is provided and the fuel injection amt. is controlled according to the alcohol density in the fuel detected by the sensor A in the alcohol internal combustion engine using an alcohol mixed fuel as the fuel. The fuel injection start time is variably set on each cylinder by an injection start time variable control means C so that the fuel injection completion time fed from the fuel injection means B provided on each cylinder may become the specified injection completion time aligned to the specified stroke of each cylinder. In this case, good combustibility is always secured by providing an injection completion time variable means D further and making the specified injection completion time freely settable variably according the this detected alcohol density. |
