An engine unit includes an engine including a cylinder injection valve that sprays fuel into a combustion chamber and an ignition plug that is able to ignite fuel sprayed from the cylinder injection valve. When expansion stroke injection drive of performing final fuel injection from the cylinder injection valve in an expansion stroke and igniting the fuel using the ignition plug in synchronization with the fuel injection in the expansion stroke is performed, upper and lower limits of an ignition timing are guarded such that the ignition timing is in a predetermined range centered on a final fuel injection start timing at a final determination timing of the ignition timing.

Engine unit

An electric load medium works at a generation voltage of a generator while at least one processor is controlling the generation voltage of the generator considering a traveling state of a vehicle. The generation voltage of the generator is controlled considering the traveling state of the vehicle, when a first condition that a value that indicates a state of charge of a battery of the vehicle that is charged by power generated by the generator is less than or equal to the predetermined threshold is satisfied, and a second condition that the vehicle is during deceleration is satisfied. Otherwise, the generation voltage of the generator is controlled considering working of the electric load medium.
