Abstract:
1. A diesel particulate filter construction for filtering particulate from a flow of exhaust, comprising: a first layer of electrically resistive filter material being positioned substantially transverse to the flow of exhaust with particulate therein and having a first end and a second end; the first end of the first layer providing a first terminal; a second layer of electrically resistive filter material being positioned substantially transverse to the flow of exhaust with particulate therein and having a first end and a second end; the first end of the second lever providing a second terminal; the second layer being electrically connected to the first layer with the second end of the first layer connected to the second end of the second layer; means attached to the first terminal of the first layer and the first terminal of the second layer for applying an electrical current through the first layer and the second layer in series to heat the first layer end the second layer above the combustion point of entrapped diesel particulate; the first layer and the second layer being positioned such that when an electrical current is applied through the first layer and the second layer, sufficient heat is generated to bum off entrapped particulate.
