Abstract
A fuel injector assembly has an outer body that is fixed to the cylinder head and an inner valve that moves to a fixed open position to discharge a fuel/compressed air or gas mixture into the combustion chamber. A control sleeve surrounds the injector body and is axially movable with respect to it to various positions to interact with the spray pattern of the fuel mixture being discharged from the nozzle to vary the shape or pattern of the fuel spray as a function of different engine operating conditions.
