Abstract
A combination emission abatement assembly includes a first emission device such as a NOx trap and a second emission abatement device such as a soot particulate filter. Reformate gas from a fuel reformer is used to selectively regenerate both the NOx trap and the soot particulate filter. A method of operating an emission abatement device is also disclosed.
