Abstract

A high frequency pulsed fuel injector is disclosed. The fuel injector incorporates a resonance tube in outlet fluid communication with a fuel nozzle. During operation the resonance tube provides a pulsating output which is directed into the fuel nozzle. The pulsating output of the resonance tube perturbs the flow of fuel in the fuel nozzle, effectively breaking it up into discrete slugs or chunks for subsequent combustion in a combustion chamber. The combustion process is greatly enhanced by this breakup of the fuel jet, improving combustion efficiency as well as reducing undesirable emissions.
