A liquid cooled reduction unit includes a diesel exhaust fluid (DEF) injection valve. The valve includes an end portion extending to a distal end. The valve is configured to receive a DEF and force the DEF to exit at the distal end such that the DEF is then directed and applied to an exhaust stream of a vehicle engine. A coolant jacket is selectively filled with a coolant and has an outer side and an inner side. The inner side of the jacket faces a length of the end portion and is separated from the length of the end portion by an air gap.

Liquid cooled reductant dosing unit

A fuel component assembly having a fuel component disposed between a base and a cover, which prevent fluid communication to an exterior thereof. The fuel component defines at least one aperture, the base supports the fuel component and defines a passage in communication with the at least one aperture. The cover is located proximate the base. A securement having a projection and the receiver that engage to form a fluid tight seal. The projection is radially disposed about a longitudinal axis of the fuel component, and the receiver continuously engages the projection. The projection being disposed on one of the cover and the base, and the receiver being disposed on the other of the cover and the base. The fuel component assembly allows for a method of encapsulating a fuel component within a fuel supply. The method can be achieve by defining a passage within a base of an assembly; seating the fuel component within the passage; providing a cover that is contiguous with the base; and welding the cover to the base to form a hermetic seal. The fuel component assembly also provides a method of regulating a fuel supply. The method can be achieved by encapsulating a fuel component within a passage defined by a continuous wall of a housing; and controlling the pressure of fuel within the passage with the fuel component.
