Abstract
A subassembly of a fuel injector that allows spray targeting and distribution of fuel to be configured using non-angled or straight orifice having an axis parallel to a longitudinal axis of the subassembly. Metering orifices are located about the longitudinal axis and defining a first virtual circle greater than a second virtual circle defined by a projection of the sealing surface onto the metering disc so that all of the metering orifices are disposed outside the second virtual circle within one quadrant of the circle. A channel is formed between the seat orifice and the metering disc that allows the fuel injector to target fuel spray generally within an arcuate sector of at least 90 degrees about the longitudinal axis of the metering disc. A method of targeting is also provided.
