Abstract
A diesel dosing module utilizes a diesel fuel shut-off valve, a diesel fuel dosing valve to provide dosing fuel to the inlet of a diesel oxidation catalyst and an air purge valve to purge fuel from a dosing line attached to the diesel dosing module and from a nozzle attached to a distal end of the dosing line. The valves are attached to a housing manifold which is remotely positionable from the nozzle and the high heat areas of the vehicle.
