ジン。 First, second, and third intake ports are branched from the main intake port, and the first intake port is a normally open intake port that generates a swirl in the intake air supplied into the combustion chamber. The intake port has an intake control valve that opens only in the high-load, high-speed range of the engine, and is an intake port that supplies straight intake air into the combustion chamber, and the third intake port has a main fuel injected with gasoline fuel. An injection valve is provided, and each of the first, second and third intake ports is connected to a combustion chamber via a first, second and third intake valve, respectively, and the third intake valve is opened. The opening timing of the first intake valve is delayed from the opening timing of the first intake valve, and the main intake port is further provided with an auxiliary fuel injection valve that injects alcohol fuel, and the fuel injected from the auxiliary fuel injection valve is injected into the first intake valve. and a second intake valve, and the auxiliary fuel injection valve is configured to operate only in a high-load, high-speed range of the engine.
