ABSTRACT:
Controlling fuel injectors to create varying injection rates and injection rate shapes typically involves using multiple control valves to control fuel pressure and check valve opening pressure independently. The fuel injector of this application uses a single control valve positioned between a fuel supply passage and a tip supply passage. The control valve has at least three positions. In a second position allowing a first maximum fuel injection rate and allowing a second maximum fuel injection rate in a third position.
