Claim 3:
4. 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 the set period is a period in which a crankshaft of the internal combustion engine is rotated by a predetermined number of times.
