Abstract
An apparatus, system, and method are disclosed for utilizing engine-generated heat in a NO-adsorber system. The apparatus may comprise a combustion device generating a heated exhaust stream. The apparatus may include a catalytic component that initiates at least one exhaust conditioning reaction within the heated exhaust stream. The catalytic component is fluidly coupled to the engine with a downpipe segment configured to preserve a minimum temperature at the catalytic component inlet based on specified operating conditions for the combustion device. The apparatus may also include a NOx-adsorber fluidly coupled to the catalytic component with a second downpipe segment.
