Embodiment Construction

[0017] The following description is merely exemplary in nature and in no way limits the disclosure, its application and uses. For purposes of clarity, the same reference numbers will be used in the drawings to refer to similar elements. As used herein, the term module refers to an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (common, dedicated, or group) and memory that executes one or more software or firmware programs, combinational logic circuits, and / or provides the described other appropriate elements of the function. The phrase at least one of A, B, and C, as used herein, should be construed to mean a logical (A or B or C) using a non-exclusive logical or. It should be understood that steps within a method may be executed in different order without altering the principles of the present disclosure.

[0018] Referring now to FIG. 1 , a cross-sectional view of a portion 10 of a particulate filter (PF) is shown. The PF includes a plu...

Abstract

The invention relates to a diesel particle filter (DPF) heater attachment mechanisms, and provides a intake-exhaust filter system and method for making the same. The exhaust filter system includes a particulate filter (PF) that is disposed downstream from an engine. The PF filters particulates within an exhaust from the engine. A heating element heats particulate matter in the PF. A fastener limits expansion movement of the heating element relative to the PF.

Description

[0001] Certain subject matter of this application was developed under Contract No. DE-FC-04-03AL67635 awarded by the Department of Energy. The US Government has certain rights in this invention. technical field [0002] The present disclosure relates to particulate filters and, more particularly, to heater fitting techniques for such particulate filters. Background technique [0003] The background introduction provided herein is provided to present the context of the disclosure as a whole. The work of the inventors presently mentioned, with regard to aspects presented in this background section, and aspects of the presentation that may not have been prior art at the time of filing, are not expressly or implied to be prior art to the present disclosure. technology. [0004] The diesel combustion cycle produces particulates that are typically filtered from diesel exhaust by a particulate filter (PF). The PF is arranged in the exhaust system of the corresponding diesel engi...
