Abstract
An internal combustion engine includes a direct injection valve that directly inject gaseous fuel from an injection hole into a cylinder by separating a needle from a seat, and a blow-by gas treating device that recirculates blow-by gas from a crankcase to an intake passage. The control device executes a suction process of suctioning gas in the cylinder into an injection hole of the direct injection valve when the blow-by gas is being recirculated by the blow-by gas processing device.
