Abstract

Official abstract text for this publication.

The present disclosure provides an improved system and method of operating a fuel injector of an engine to provide at least two different types of fuel spray in a combustion chamber of the engine by application of ultrasonic pulses to fuel in the fuel injector during an injection event. A first type of spray includes larger droplets that reduce the effective diffusion combustion area around the droplets and a second type of spray includes relatively small droplets that increase the effective diffusion combustion area around the droplets.

First claim

Opening claim text (preview).

We claim: 1. A fuel system for supplying a fuel to a combustion chamber of an internal combustion engine, the system comprising: a fuel injector including an injector body having a longitudinal axis, a nozzle housing secured to the injector body and including at least one injector orifice in communication with the combustion chamber, a fuel injector cavity, a nozzle valve element extending longitudinally along the fuel injector, an actuator adapted to receive an injection signal a…
