ABSTRACT:
A fuel injection valve comprising, a fuel swirler (6) providing a swirling force to fuel, a fuel nozzle (5) injecting the swirling fuel, an air swirler (7) including an air swirling chamber (7B) and air nozzles (7A) disposed downstream the fuel nozzle (5) adjacent the outlet port (7C) thereof, the air nozzles (7A) are constituted to introduce air into the air swirling chamber (7B) and to cause a swirling air flow therein directed opposite to the direction of the swirling fuel flow from the fuel nozzle (5) whereby the swirling air flow is caused to collide with the swirling fuel flow immediately after being injected from the fuel nozzle (5) in the air swirling chamber (7B) to thereby enhance atomization of the fuel and to properly decelerate the moving velocity of the injected atomized fuel.
