燃機関。 It is equipped with three intake valves consisting of a first intake valve, a second intake valve and a third intake valve, and three intake passages consisting of a first intake passage, a second intake passage and a third intake passage. A first intake passage for generating a swirling flow inside the room is connected to the combustion chamber through the first intake valve, and a second intake passage connected to the combustion chamber through the second intake valve is connected to the combustion chamber through the second intake valve. An intake control valve that opens during the intake stroke is disposed, and a main fuel injection valve is disposed in a third air passage connected to the combustion chamber via the second intake valve, and the first intake valve and the second intake valve open during the intake stroke. In a fuel injection internal combustion engine in which the third intake valve opens from near the top dead center to the beginning of the compression stroke, and the third intake valve opens from near the center of the intake stroke to the beginning of the compression stroke,
The engine load is predetermined by controlling the main fuel injection valve and the auxiliary fuel injection valve according to the engine load. When the engine load is smaller than the load, the mixture is supplied into the combustion chamber only from the third intake passage, and when the engine load is larger than the predetermined load, the mixture is supplied into the combustion chamber from the first intake passage, the second intake passage, and the third intake passage. A fuel-injected internal combustion engine with multiple intake valves adapted to supply fuel.
