CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

In an internal combustion engine, fluctuations in combustion torque are suppressed to reduce vibration and prevent deterioration of ride comfort of a driver. Therefore, a control device of an internal combustion engine having a plurality of cylinders (a first cylinder , a second cylinder , a third cylinder , and a fourth cylinder ) includes a combustion state detection unit for detecting whether the plurality of cylinders are in a normal combustion state or a flame-out state, and a control device which controls driving of a fuel pump that is a load of a combustion torque generated by the cylinder . The control device suppresses the driving of the fuel pump at a predetermined combustion timing of the cylinders to of the flame-out state in a case where it is determined that any one of the cylinders to among the plurality of cylinders is in the flame-out state.
