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 fuel injection valve is disposed in a third intake passage connected to the combustion chamber via a third intake valve. In a fuel injection internal combustion engine in which the valve is opened from near top dead center to the beginning of the compression stroke, and the third intake valve is opened from near the center of the intake stroke to the beginning of the compression stroke, the valve diameter of the first intake valve is equal to the diameter of the second intake valve. and a plurality of intake valves that are formed larger in diameter than the third intake valve so that the fuel injection completion timing of the fuel injection valve is gradually advanced from the end of the intake stroke to the beginning of the intake stroke as the engine speed increases. A fuel-injected internal combustion engine with
