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.

Abstract: A method of purging fuel supply components for a combustion chamber of a regeneration assembly (36) is disclosed. A regeneration cycle is performed during which fuel is supplied from a fuel source (22) to the combustion chamber with fuel supply components including a fuel supply circuit (48) and at least one fuel injector unit (40). At least a first purging cycle is initiated to purge residual fuel from the fuel supply components. During the purging cycle, a flow of purging gas is directed to the at least one fuel injector unit (40) to purge residual fuel from the at least one fuel injector unit (40). Also during the purging cycle, a flow of purging gas is directed to the fuel supply circuit (48) to purge at least a portion of the fuel in the fuel supply circuit (48) toward the fuel source (22).
