Abstract
The electronic control unit performs a retarding process of retarding the ignition timing when the fuel pressure decreases, and lowers the peak of the combustion pressure in the cylinder, thereby suppressing the inflow of the combustion gas to the injector. Further, the electronic control unit performs an increasing process of increasing the injection amount of the hydrogen gas together with the retarding process, thereby suppressing the torque decrease of the engine due to the retard of the ignition timing.
