ABSTRACT:
An improved auxiliary heat source for use in an engine cold start emission reduction system includes a flame containment chamber having at least one wall formed of a porous foam material that confines the flame within a predetermined chamber while permitting heat therefrom to emerge and flow to an exhaust system catalyst or, in the case of diesel engines, a particulate trap.
