    Abstract: An emissions control substrate. The emissions control substrate includes a first end in receipt of exhaust from an engine, and a second end from which exhaust exits the substrate. The second end is opposite to the first end. A plurality of channels are defined by sidewalls. The channels are arranged between the first end and the second end to direct exhaust from the engine through the emissions control substrate. The sidewalls at least one of filter and treat exhaust particulates as the exhaust passes through the sidewalls. The plurality of channels include at least one first channel defined by sidewalls that curve inward along lengths thereof from the first end to the second end.

    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: The present teachings provide for an exhaust system device including a substrate body, a pair of electrical leads, and a resistance heating element. The substrate body can include a plurality of first walls that can extend between an upstream end and a downstream end of the substrate body. The substrate body can include a plurality of second walls that can be transverse to the first walls and can extend between the upstream end and the downstream end. The first and second walls can define a plurality of channels. The pair of electrical leads can be configured to be coupled to a power source. The resistance heating element can be disposed within or on at least one of the first or second walls and can be electrically coupled to the electrical leads to receive power from the electrical leads.

    Abstract: A system for particulate filter regeneration includes a pre-converter universal heated exhaust gas oxygen (UHEGO) sensor disposed upstream from a three-way catalytic (TWC) converter and a particulate filter (PF), and a post-converter UHEGO sensor disposed downstream from the TWC converter and upstream from the PF. An engine controller for an internal combustion engine (ICE) and in communication with the pre-converter UHEGO sensor and the post-converter UHEGO sensor is included. The engine controller is configured to determine an amount of particulate mass accumulated in the PF during operation of the ICE and deactivate at least one of a plurality of cylinders of the ICE such that a deactivated cylinder intake air (DCIA) pass-through volume flows through the at least one deactivated cylinder and into the TWC converter and the PF. The DCIA pass-through volume is a function of the determined amount of particulate mass accumulated in the PF.
