Abstract
A fuel injector includes an injector housing defining a longitudinal axis extending between a first axial injector end and a second axial injector end. The injector housing includes an upper body piece forming the first axial injector end and including a fuel connector defining a connector axis intersecting the longitudinal axis. The injector housing further includes a nozzle having formed therein a plurality of spray outlets, and including a nozzle terminal tip. An injector full diameter (FD) is defined by the upper body piece. An axial distance (AD) is defined between an intersection of the connector axis and the longitudinal axis, and the nozzle terminal tip. A ratio of AD to FD is from 4.8 to 5.1.
