Resistive heater geometry and regeneration method for a diesel particulate filter

Patent Phelps, Amanda [Malibu, CA]; Kirby, Kevin W [Calabasas Hills, CA]; Gregoir, Daniel J [Thousand Oaks, CA]

One embodiment of the invention includes a diesel particulate filter comprising a first face and a second face; a bottom electrode layer formed over the first face of the diesel particulate filter; a middle resistive layer formed over a portion of the bottom electrode layer; and a top electrode layer formed over a portion of the middle resistive layer.

Electrically resistive coating for remediation (regeneration) of a diesel particulate filter and method

Patent Phelps, Amanda C [Malibu, CA]; Kirby, Kevin K [Calabasas Hills, CA]; Gregoire, Daniel J [Thousand Oaks, CA]

A resistively heated diesel particulate filter (DPF). The resistively heated DPF includes a DPF having an inlet surface and at least one resistive coating on the inlet surface. The at least one resistive coating is configured to substantially maintain its resistance in an operating range of the DPF. The at least one resistive coating has a first terminal and a second terminal for applying electrical power to resistively heat up the at least one resistive coating in order to increase the temperature of the DPF to a regeneration temperature. The at least one resistive coating includes metal and semiconductor constituents.

Diesel particulate filter (DPF) regeneration by electrical heating of resistive coatings

Patent Williamson, Weldon S [Malibu, CA]; Gonze, Eugene V [Pinckney, MI]

An exhaust system that processes exhaust generated by an engine includes a diesel particulate filter (DPF) that is disposed downstream of the engine and that filters particulates from the exhaust. An electrical heater is integrally formed in an upstream end of the DPF and selectively heats the exhaust to initiate combustion of the particulates within the exhaust as it passes therethrough. Heat generated by combustion of the particulates induces combustion of particulates within the DPF.

Zone heated diesel particulate filter electrical connection

Patent Gonze, Eugene V [Pinckney, MI]; Paratore, Jr., Michael J. (Howell, MI)

An electrical connection system for a particulate filter is provided. The system includes: a particulate filter (PF) disposed within an outer shell wherein the PF is segmented into a plurality of heating zones; an outer mat disposed between the particulate filter and the outer shell; an electrical connector coupled to the outer shell of the PF; and a plurality of printed circuit connections that extend along the outer surface of the PF from the electrical connector to the plurality of heating zones.

Diesel particulate filter with zoned resistive heater

Patent Gonze, Eugene V [Pinckney, MI]

A diesel particulate filter assembly comprises a diesel particulate filter (DPF) and a heater assembly. The DPF filters a particulate from exhaust produced by an engine. The heater assembly has a first metallic layer that is applied to the DPF, a resistive layer that is applied to the first metallic layer, and a second metallic layer that is applied to the resistive layer. The second metallic layer is etched to form a plurality of zones.
