Abstract: PROBLEM TO BE SOLVED: To increase the fuel injection rate of the fuel injection valve provided in the air intake passage as the concentration of alcohol in the fuel increases, protects the cylinder fuel injection valve, and improve the operating performance of the dual injection type internal combustion engine for FFV. SOLUTION: The internal combustion engine 10 is equipped with a port injection valve 16 to inject fuel into the air intake passage 14 and a cylinder injection valve 18 to inject fuel into the cylinder 12. The ECU 40 causes either or both of fuel injection valves 16 and 18 to inject fuel according to the operating status of the internal combustion engine 10. In this case, the ECU 40 increases the port injection rate α as the concentration of alcohol Ma in the fuel is higher. This can increase the fuel consumption of the port injection valve 16 to improve fuel consumptions and torque fluctuations, and adequately inject fuel into the cylinder injection valve 18 to prevent deposition of deposits and the like.
