Abstract: The present teachings provide for a catalytic converter for modifying the composition of exhaust gas of an engine. The catalytic converter includes a housing, a substrate body, and a first layer of catalyst material. The housing can define an inlet for receiving the exhaust gas from the engine, a main chamber in fluid communication with the inlet, and an outlet in fluid communication with the main chamber for exhausting the modified exhaust gas. The substrate body can be disposed within the central chamber and can define a plurality of flow channels. The flow channels can provide fluid communication between the inlet and the outlet. The first layer of catalyst material can provide a first section of the flow channels with a first overall wall thickness that is greater than a second overall wall thickness of a second section of the flow channels.

Abstract: A muffler integrated type gasoline particulate filter includes a filter having first and second surfaces and first channels and second channels alternately arranged, each of the first channels being closed at the second surface and each of the second channels being closed at the first surface, the filter collecting exhaust gas particulates when exhaust gas passes through a wall surface disposed between the first and second channels. The muffler integrated type gasoline particulate filter further includes protruding walls formed on an inner wall surface of each of the first and second channels in a longitudinal direction thereof. The protruding walls reduce noise of the exhaust gas flowing along each of the first and second channels.

Abstract: A system for treating diesel exhaust is disclosed. The system includes a first filter including layers of filtration material positioned between layers of corrugated metallic foil. The metallic foil defines a honeycomb arrangement of longitudinal passageways from an upstream end to a downstream end and also openings for allowing exhaust to pass between adjacent longitudinal passageways of the metallic foil. The filtration material is positioned such that exhaust between the adjacent longitudinal passageways passes through the filtration material. The metallic foil also includes flow diverting structures to divert flow within the longitudinal passageways through the openings. A second filter is positioned downstream from the first filter. The second filter defines a honeycomb arrangement of longitudinal passageways. The longitudinal passages are selectively plugged adjacent upstream and downstream ends to force flow radially through walls between the longitudinal passages of the second filter.
