射装置。 The combustion chamber of each cylinder is equipped with two intake valves, and the intake passage is partitioned into a main intake port and a sub-intake port by a partition wall near the intake valve. In a fuel injection system for an internal combustion engine that generates a swirl in the combustion chamber by making the amount of intake air flowing into the port larger than that of the sub-intake port, a single injector is provided immediately upstream of the partition wall, and injection is performed from this injector. An internal combustion engine characterized in that the nozzle is configured so that the fuel spray spreads in two directions by sandwiching the partition wall, and the amount of fuel injected into the main intake port is larger than the amount of fuel injected into the auxiliary intake port. Fuel injection device.
