Abstract
A manifold exhaust processor includes a pair of substrates mounted within the interior of an exhaust manifold housing and aligned in end-to-end relation to permit each substrate to treat the combustion product exhausted from a different group of engine cylinders and to equalize the temperatures of the outer skin and centerline portion of the substrate to reduce thermal stress. A common outlet is provided to exhaust the treated combustion product. The first substrate is mounted in a first chamber of the manifold housing in close proximity to a first inlet to cause combustion product to be introduced into the first chamber in a direction toward a side wall of the first substrate to promote tangential flow about the side wall and around the substrate. Likewise, the second substrate is mounted in a second chamber of the manifold housing in spaced-apart, end-to-end relation with the first substrate and in close proximity to a second inlet to cause combustion product to be introduced into the second chamber in a direction toward a side wall of the second substrate, and also to promote tangential flow.
