Pulsed air assist fuel injector

摘要

A fuel injector (10) 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 means (20) , fuel inlet means (68), mixing chamber (38) and control means for controlling the simultaneous introduction of air and fuel into the mixing chamber. The control means 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. <IMAGE>
