エアアシスト式の燃料噴射装置。 Air-assisted fuel injection in which one fuel injector installed at the intake port of an internal combustion engine is equipped with two fuel nozzles and an assist air nozzle that introduces assist air in a direction that intersects the fuel injection direction at each nozzle. In the device, the assist air nozzle to the fuel nozzle on the side of the spray that is deflected toward the intake port wall due to the influence of the intake air flow is closed during operation with a large amount of intake air flowing through the intake port to the assist air piping that connects the air source to the assist air nozzle. An air-assisted fuel injection device for an internal combustion engine, characterized by being provided with an on-off valve.
