ABSTRACT:
A collision type of fuel injection nozzle that ensures full frontal collision between jets of fuel injected from the opposed second injection nozzle holes is provided, and a method of manufacturing the nozzle. The method includes forming fuel inlets that extend from the fuel passage and avoid the collision recess, simultaneously forming the at least one pair of injection nozzles holes in a straight line that intersects the fuel inlets and the collision recess and then fixing a cap over at least a peripheral portion of the injection holes. This manufacturing method permits the nozzle holes to be formed at the same time ensuring alignment of the outlets for collision and highly uniform atomization.
