ABSTRACT:
A dosing device is provided that is suitable for administering a reagent into an exhaust chamber of an internal combustion engine. The device comprises a nozzle body and an insulating jacket wherein the jacket is mounted to the nozzle body at one or more mounting points, and wherein the dosing device is adapted to engage with a port located in the wall of an exhaust chamber. The insulating jacket defines a compartment, which can comprise an insulating material or can be substantially evacuated. The dosing device of the invention is advantageously insulated from the elevated temperatures in the surrounding environment, thereby allowing for the reagent to be maintained at an optimal working temperature range.
