PROBLEM TO BE SOLVED: To quickly reduce fuel pressure in a high pressure fuel pipe after recovering a fuel cut, without reducing exhaust performance, and without varying torque, with a simple constitution requiring no additional part. SOLUTION: This control device has the high pressure fuel pipe supplying high pressure fuel via a check valve, and supplying fuel to a fuel injection valve. When starting fuel cut recovery operation for resuming fuel injection from fuel cut operation for temporarily stopping the fuel injection, a fuel injection quantity is increased while reducing combustion efficiency, and efficiency reducing operation for increasing the intake air volume is performed (Step 20 and 21).
