A basic fuel quantity calculation means for calculating, an overheat prevention fuel increase value calculation means for calculating a fuel increase value for overheat prevention according to operating state parameters in order to prevent overheating of the engine exhaust system, and an overheat prevention fuel increase value calculation means for securing engine output. an output securing fuel increase value calculation means for calculating a fuel increase value for securing output according to operating state parameters, and correcting the basic fuel amount based on these increase values;
A fuel amount adjusting means for supplying the corrected final fuel amount to the internal combustion engine, and a predetermined operating range in which the current operating state requires an increase in fuel amount to prevent overheating and does not require an increase in fuel amount to secure output. Exhaust system cooling control means that guides the vehicle running air to the outside of the engine exhaust system to cool it; and when the exhaust system cooling means is activated, the overheat prevention fuel increase value calculation means calculates A control device for an internal combustion engine, comprising overheat prevention fuel increase value correction means for correcting an increase value by decreasing the increase value.
