Embodiment Construction

[0033] Reference is now made to the drawings, in which the illustrations are for purposes of illustration of certain exemplary embodiments only and are not intended to be limiting thereof. figure 1 Exhaust aftertreatment system 40 and accompanying control systems implemented in control module 10 constructed in accordance with embodiments of the present invention are schematically illustrated. In one embodiment, exhaust aftertreatment system 40 is shown fluidly coupled to exhaust manifold 39 of internal combustion engine 240 , although the methods described herein are not so limited. In the drawings, the same symbols indicate the same elements.

[0034] In one embodiment, engine 240 is a multi-cylinder direct injection four-stroke internal combustion engine operating at a lean air / fuel ratio to generate mechanical power that may be transmitted to the driveline. An air intake system directs incoming air to intake manifold 29 which directs and distributes the air into intake pa...

Abstract

A device for filtering particulates from an exhaust gas feedstream of an internal combustion engine includes a filter substrate having a multiplicity of alternately closed parallel flow passages having porous walls oriented parallel to a flow axis of the exhaust gas between an inlet and an outlet thereof, wherein subsets of the flow passages are associated with respective ones of a plurality of zones, a flow control valve to control flow of exhaust gas to each of the plurality of zones, a multi-zone heating element including a plurality of individually activated heating elements each corresponding to one of the plurality of zones.

Description

technical field [0001] The present invention relates to exhaust aftertreatment systems, and more particularly, to monitoring particulate filters of exhaust aftertreatment systems. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] An aftertreatment system for managing and treating an exhaust gas feedstream may include a particulate filter device that removes particulate matter, such as elemental carbon particles, from the feedstream. Known applications for particulate filter devices include internal combustion engines operating on the lean side of the stoichiometric point, including, for example, compression ignition (diesel) engines and lean burn spark ignition engines. Known particulate filter devices require periodic regeneration to oxidize and remove filtered particulate matter from the particulate filter device. Regeneration may require operatio...
