Embodiment Construction

[0027] The following description is exemplary only in nature and is not intended to limit the disclosure, its application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts or features.

[0028] The term "module" as used herein refers to an Application Specific Integrated Circuit (ASIC), a circuit, a processor (shared, dedicated, or group processor) and memory, combinational logic circuits, and / or other suitable components that provide the described functionality.

[0029] Wireless regeneration refers to the transfer of electromagnetic energy to the PM filter or PM filter heating assembly without the use of wire contact. Wireless regeneration can include direct absorption of electromagnetic energy, such as microwave heating and radiant heating.

[0030] To reduce power consumption and increase PM filter durability during regeneration, individual zones can be heated. Individual regions can be ...

Abstract

One assembly of a wireless subarea particle material filter regeneration control system comprises a particle material (PM) filter which comprises the following components: an upstream side which is used receiving the discharged air; a downstream side; and a plurality of areas. An absorbing layer absorbs the energy of microwave in N frequency areas and is installed at the upstream side. N is an integer. A frequency selection filter in the assembly is provided with M frequency selection subareas and receives the energy of microwave in N frequency areas. M is an integer. One frequency selection subarea in the M frequency selection subareas allows the energy passing of microwave in one frequency area of N frequency areas and does not allow the energy pass of microwave in other frequency areasof N frequency areas.

Description

[0001] For related applications see [0002] This application claims the benefit of US Provisional Application 60 / 973,284, filed September 18, 2007, the disclosure of which is hereby incorporated by reference. [0003] Statement of Government Rights [0004] This disclosure was formed pursuant to US Government Contract DE-FC-04-03AL67635 with the Department of Energy (DOE). The United States Government has certain rights in this disclosure. technical field [0005] The present invention relates to a particulate matter (PM) filter, and more particularly to an electrothermal PM filter. Background technique [0006] The statements in this section merely provide background information related to the present disclosure which may not constitute prior art. [0007] Engines such as diesel engines generate particulate matter (PM), which is filtered out of exhaust gas by a PM filter. The PM filter is provided in the exhaust system of the engine. PM filters reduce the emission of ...
