ABSTRACT:
A fuel injector has a swirl plate about a valve assembly, including a valve seat with an orifice and a valve pin. When the valve is opened, the fuel is swirled by the swirl plate for passage through the orifice. The orifice has a portion which is angled relative to the axis of the injector to provide a conical swirling spray pattern having a conical spray axis angularly related to the axis of the injector. In another form, the orifice is on-axis with the injector and receives a bent tube having an upstream on-axis portion and a downstream angled portion to direct the swirling conical spray at an included obtuse angle relative to the axis of the injector.
