Abstract
The disclosure provides an improved fuel injector and method of operating the fuel injector to provide at least two different types of fuel spray to a combustion chamber of an internal combustion engine. The two types of spray are formed by providing a first fuel pressure to the fuel injector during a first portion of an injection event at a first pressure and providing a second fuel pressure to the fuel injection during a second portion of the injection event, and maintaining a substantially constant fuel flow rate throughout the injection event.
