摘要:
An exhaust system can comprise a NOx adsorber, a reformer disposed upstream of a NOx adsorber and in fluid communication with a fuel source, a first valve for controlling the introduction of the fluid to an exhaust conduit; and a particulate filter disposed upstream and in fluid communication with the NOx adsorber and downstream an in fluid communication with the reformer such that the first valve controls introduction of fluid to the exhaust conduit upstream of the particulate filter. The reformer can be designed to generate a fluid comprising sufficient thermal energy, hydrogen, and carbon monoxide. Optionally, the particulate filter can be designed to be regenerated by the thermal energy and to adsorb a sufficient amount of the thermal energy to reduce the temperature of a gas stream comprising the fluid from a first temperature of about 600° C. to about 1,000° C. to a second temperature of less than or equal to about 500° C.
