Title:
ELECTRICALLY HEATED CATALYST
Document Type and Number:
WIPO Patent Application WO/2013/057792
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress flow of electricity in a case (5) for an electrically heated catalyst (1). This electrically heated catalyst (1) is provided with: a heating element (3) that generates heat by the flow of electricity; a case (5) that accommodates the heating element (3); an inner tube (4) that is provided between the heating element (3) and the case (5) and insulates electricity; an inside mat (62) provided between the heating element (3) and the inner tube (4); and an outside mat (64) provided between the inner tube (4) and the case (5). The inner tube (4) is provided with a tube shaped part (42) that is provided around the heating element (3) and formed parallel to the center axis (A) of the heating element (3) and a downstream side inclined part (43) that is provided on the downstream side of the tube shaped part (42) and in which the inside diameter becomes smaller toward the downstream side. A downstream side curved part (45), which is the boundary between the tube shaped part (42) and the downstream side inclined part (43), is provided in proximity to a downstream side end part (64A) of the outside mat (64).
