Abstract
A method and system for introducing supplemental material to an exhaust aftertreatment device, including: a delivery system, an air pump operable to input pressurized air to the delivery system, and a turbosupercharger of an internal combustion engine operable to deliver pressurized air to an inlet of the air pump. The supplemental material introduced to the exhaust aftertreatment device is pressurized by the pressurized air input from the air pump, and the air inlet to the air pump is pressurized by the turbosupercharger for the internal combustion engine. The delivery system uses existing pressurized air generated within the engine system from the turbosupercharger to supplement air pressure supplied to the turbine-style air pump used by the delivery system. The supplemental material may comprise ammonia, hydrogen, carbon monoxide, or urea.
