Abstract

The present invention relates to an inductively heated particulate matter filter regeneration control system, including a particulate matter (PM) filter with an upstream end for receiving exhaust gas, a downstream end and zones. The system also includes a heating element. A control module selectively activates the heating element to inductively heat one of the zones.

Description

[0001] Cross References to Related Applications [0002] [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 973,280, filed September 18, 2007. The disclosures of the aforementioned applications are incorporated herein by reference. [0003] Statement of Government Rights [0004] [0001] This invention is made pursuant to US Government Treaty DE-FC-04-03 AL67635 with the Department of Energy (DoE). The US Government has certain rights in this invention. technical field [0005] [0002] The present invention relates to particulate matter (PM) filters, and more particularly to electrically heated PM filters. Background technique [0006] [0003] The statements in this subsection merely provide background art related to the present invention and therefore may not constitute prior art. [0007] [0004] Engines, such as diesel engines, generate particulate matter (PM), which is filtered from the exhaust gas by a PM filter. The PM filter is arranged...
