Abstract
An exhaust processor assembly includes an exhaust pipe and a substrate for treating emissions contained in combustion product emitted from an engine exhaust. The assembly also includes a second pipe for providing a passageway receiving combustion product and the substrate means is positioned in the passageway to treat emissions passed therethrough. The assembly further includes an apparatus for positioning the second pipe in the interior region of the exhaust pipe so that thermal transfer between the substrate and the second pipe is minimized in order to maximize retention of thermal energy by the substrate resulting from the combustion product traveling through the passageway.
