Exhaust gas treatment substrates, and systems and methods including the same are provided. Catalyst substrates having flow properties where in configuring an outer, peripheral zone, more exhaust gas flows through a central zone as compared to the outer, peripheral zone. The outer, peripheral zone can have a trapping or adsorbing material on surfaces of its passages, or it can have a longer axial length as compared to the inner zone, or its passages can have smaller openings as compared to the inner zone. In one embodiment, an overcoat containing a trapping material such as a hydrocarbon trap is applied to an inlet end. In another embodiment, catalyst having an oxygen storage component is applied to an outlet end.

Multi-zoned catalyst compositions

An OBD system is provided for monitoring an ozone depletion system that includes a catalyst coating containing MnO applied to a heat exchange surface on a moving vehicle over which atmospheric air passes. A physical characteristic of the catalyst coating or a material containing a physical characteristic within the catalyst coating is sensed to determine the presence or absence of the catalyst coating for detecting catastrophic failure of the ozone depleting system and/or degradation or wear of the catalyst coating to ascertain the efficiency of the catalyst coating.

System for sensing catalyst coating loss and efficiency

In an exhaust gas system comprising a hydrocarbon trap (28) and a downstream catalyst zone (30), a heat exchange catalyst member (10) is incorporated into the system to provide heat exchange between the exhaust gas and air that is pumped through the heat exchange catalyst member (10). The heated air is injected into the exhaust gas stream to facilitate the oxidation of hydrocarbons in the downstream catalyst zone. The heat exchange catalyst member (10) defines two separate flow paths therethrough, one of the flow paths containing a catalyst zone for the exhaust gas. In an alternative embodiment, the injected air is heated by a heat exchange trap (28') or by a separate heating element (62).
