Claim 0:
1. A control device of an internal combustion engine in which a control target is the internal combustion engine including a cylinder in which an air-fuel mixture of gaseous fuel and intake air is burned, an intake passage connected to the cylinder, and a supercharger that supercharges the intake air, wherein the control device executes:
a first process of determining whether a backfire occurs based on an operating state of the internal combustion engine; and
a second process of performing supercharging with a smaller supercharging pressure when a backfire has occurred in a predetermined set period before supercharging is performed by the supercharger than when a backfire has not occurred in the set period, wherein in the second process, the supercharging pressure is decreased as an occurrence frequency of the backfire in the set period is higher.
