Abstract:
A fuel injector including an injector tip 160 that has annular fuel flow passages and a stem 172 containing at least one fuel flow passage 174 extending from a stem fuel inlet 140 to a fuel delivery outlet 186. A first annular fuel flow cavity 142 provided in the stem near the fuel stem inlet 140, an inlet conduit 144 extends from the fuel stem inlet 140 to the annular cavity 142, the inlet conduit 144 being angled to provide a tangential flow direction to the fuel passing through the conduit 144 to the annular cavity 142. An outlet conduit 146 extends at an acute angle from the first annular cavity 142 to receive the fuel therefrom in a tangential direction. A first linear fuel conduit 148 is provided extending from the outlet conduit 146, extending axially of the stem and communicating with an injector inlet conduit 186 at the fuel delivery outlet. The injector inlet conduit 186 is angled to direct the fuel flow to a first annular passage 168 in the injector tip 160 in a tangential direction to provide a swirl to the fuel flow entering the annular passage 168 in the injector tip 160.
