ABSTRACT:
A fuel injection system includes an injector body that defines a nozzle outlet connected to a nozzle supply passage having a flow restriction. A source of fuel at a supply pressure is in fluid communication with the nozzle supply passage. A needle valve member is positioned in the injector body and is moveable between an open position in which the nozzle outlet is open, and a closed position in which the nozzle outlet is blocked. The supply pressure is of a magnitude and the flow restriction is of a size that the needle valve member moves cyclically between its closed position and its open position.
