Abstract
A system for selectively intensifying fuel for injection utilizing a fuel injector having an intensifier piston connected to a drain and a pressurized fuel source. The intensifier piston includes a control chamber co-axially positioned opposite from an intensification chamber, and a pressurization chamber co-axially positioned between the control chamber and the intensification chamber. The control chamber selectively fluidly communicates with the pressurized fuel source and the drain. The intensification chamber fluidly communicates with the pressurized fuel source and the pressurization chamber fluidly communicates with the pressurized fuel source and a nozzle assembly.
