Abstract
Official abstract text for this publication.
In a catalytic converter having a catalyst support that generates heat by being energized, short circuiting due to soot within exhaust is suppressed. A catalyst support is provided in a range of a glass coat layer that is provided on an inner surface of a tube body. A maximum diameter portion of an upstream side reduced diameter member and a maximum diameter portion of a downstream tube are positioned in the range of the glass coat layer.
First claim
Opening claim text (preview).
1 . A catalytic converter comprising: a tube body that is formed in a tube shape and forms a portion of a flow path of exhaust; an insulating layer that is provided at an inner surface of the tube body; a catalyst support that is provided at an interior of the tube body in a range of the insulating layer, and that supports a catalyst for purifying exhaust discharged from an internal combustion engine, and whose temperature is raised due to the catalyst support being energized; an upstream side combustion member of which a region, that is nearest to an inner periphery of the tube body, is positioned in the range of the insulating layer and further toward an upstream side of the exhaust than the catalyst support, and that burns soot, within the exhaust, that has adhered to the upstream side combustion member; and a downstream side combustion member of which a region, that is nearest to the inner periphery of the tube body, is positioned in the range of the insulating layer and further toward a downstream side of the exhaust than the catalyst support, and that burns soot, within the exhaust, that has adhered to the downstream side combustion member. 2 . The catalytic converter of claim 1 , wherein the upstream side combustion member is an upstream tube that is formed in a tube shape and whose diameter decreases toward an upstream side. 3 . The catalytic converter of claim 1 or claim 2 , wherein the downstream side combustion member is a downstream support that supports a catalyst for purifying the exhaust.
