Abstract
In a fuel injector, a swirl generator operates to impart a tangential or swirl component to the fuel as it is expelled from the injector. The mass of the swirl generator is minimized so as to maximize the actuating speed of the injector. The swirl generator develops a pressure drop across the generator during the time the fuel is expelled which pressure drop aids in enhancing the closure time of the injector. The swirl generator provides damping to the needle valve upon both opening and closing. The swirl generator minimizes the volume of residual fuel remaining in the injector.
