Patent ID: 7409823

Claim:
A system for introducing a supplemental material comprising reformate material from a reformer to an exhaust gas stream from an internal combustion engine, comprising: a device operable to introduce the supplemental material to the exhaust gas stream downstream of the engine; an air pump operable to input pressurized air to the device; and a turbosupercharger for the internal combustion engine operable to deliver pressurized air to an inlet of the air pump; wherein the supplemental material introduced to the exhaust gas stream is pressurized by the pressurized air input from the air pump; and wherein air inlet to the air pump is pressurized by the turbosupercharger of the internal combustion engine; and further comprising an electronic controller that is operable to monitor input from at least one sensing device comprising a differential pressure sensor, that is operable to determine a quantity of the supplemental material to be introduced to the exhaust gas stream based upon input from the at least one sensing device, and that is operable to control the device, the air pump and the turbosupercharger, such that the quantity of the supplemental material to be introduced to the exhaust gas stream is substantially completely introduced.
