射弁。 In a fuel injection valve for an internal combustion engine in which fuel injected from a fuel injection nozzle port and assist air are injected together from a constantly open fuel air injection port, the fuel is injected from the fuel injection nozzle port into the housing of the fuel injection valve. A collision wall is provided in which the mixed flow of the fuel and assist air collides with each other, and a fuel-air passageway extends from the junction part toward the fuel-air jet port. A fuel injection valve for internal combustion engines formed in the fuel air passage.
