Abstract

A fuel injector having a pulsed air assist atomizer to provide improved atomization and fuel spray targeting. The fuel injector provides a pulsed air supply, rather than a continuous air supply at the discharge of the fuel injector. The fuel injector includes an air inlet, a fuel inlet, mixing chamber and controller for controlling the simultaneous introduction of air and fuel into the mixing chamber. The controller controls an air jet to impact fuel flowing into the mixing chamber to atomize the fuel before discharge of the air-fuel mixture from the fuel injector.
