ABSTRACT:
The nozzle of a fuel injector is constructed to have a seat member and a single thin disc orifice member. A guide member affixed to the seat member guides the injector needle toward the seat in the seat member as the needle is reciprocated within the injector by pulsing the injector solenoid. Fuel is conveyed past the guide member by holes that are spaced radially outwardly from the central hole which guides the needle and that are skewed to the injector axis. As fuel passes through these skewed holes, it acquires angular momentum. The effect of this angular momentum is to increase the divergence of the column of fuel that is emitted by the single thin disc orifice member.
