射装置。 The intake port is composed of a first intake port and a second intake port separated by a partition wall, and the first intake port has a side wall surface located on the second intake port side that projects into the first intake port. It is composed of a helical intake port that gives a swirling flow to the intake air flow, and an intake control valve that is controlled to open and close depending on the engine operating state is disposed in the second intake port, and the intake control valve downstream of the intake control valve is forming a communication hole in the partition wall that communicates the first and second intake ports;
A fuel injection valve having a pair of nozzles is disposed in the communication hole, and fuel is injected from one nozzle toward the first intake valve disposed within the first intake port, and fuel is injected from the other nozzle to the second intake valve. In an internal combustion engine with a dual intake port configured to inject fuel toward a second intake valve disposed within the port, an angle formed between the injection axis of the fuel injected into the second intake port and the partition wall. A fuel injection device for an internal combustion engine with multiple intake ports, wherein the angle between the partition wall and the injection axis of fuel injected into the first intake port is smaller than the angle formed by the partition wall and the injection axis of fuel injected into the first intake port.
