Gaseous emissions treatment structures with induction heating
First Claim
1. An assembly for treating gaseous emissions comprising a honeycomb ceramic substrate body having a plurality of cells, a first set of the plurality of cells for the passage of emissions gas, discrete lengths of metal wire located in respective ones of each of a second set of the plurality of cells, and an induction heating coil mounted adjacent the substrate body for generating a varying electromagnetic field, to thereby inductively heat the discrete lengths of wire and to thereby heat the substrate body and the emissions gas.

Abstract
A gaseous emissions treatment assembly has a honeycomb ceramic substrate body with a plurality of cells for passage of exhaust gases. Respective lengths of metal wire are located in a number of the cells. An induction heating coil is mounted adjacent the substrate body for generating a varying electromagnetic field, thereby inductively to heat the lengths of wire and thereby to heat the substrate body.
