Abstract: 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.

Abstract: The present invention provides a highly durable, electrically heated catalytic converter including an inner tube on which an insulation layer is formed, wherein the insulation layer is less susceptible to damage such as cracking and peeling even when thermal stress occurs in a curvature section of the inner tube where the insulation layer is formed.

Abstract: A decrease in cost is devised at an exhaust treatment device that purifies exhaust from an internal engine by a catalyst that is heated from a catalyst support that generates heat by being energized, and that returns some of exhaust that has been purified to the internal combustion engine. A cooling member is provided at a portion of an exhaust pipe that is between an engine and an upstream catalytic converter, and a circulation pipe is branched-off from between the upstream catalytic converter and a vibration cut-off member that is at a downstream side.

Abstract: The present invention provides a highly durable, electrically heated catalytic converter including an insulation layer formed on an inner tube, wherein the insulation layer is less susceptible to cracking and peeling even when high thermal stress occurs in the insulation layer at and near the end portion of an inner tube, at upstream of a catalyst carrier.

Abstract: A catalytic converter apparatus includes a catalyst substrate that supports a catalyst for cleaning exhaust gas exhausted from an internal combustion engine, the catalyst substrate being heated by electrification; a case formed in a tubular shape, the catalyst substrate being accommodated inside the case and the case being attached to an exhaust pipe; an outer pipe provided at the case, the outer pipe being disposed at least at an upstream side of an exhaust gas flow direction relative to the catalyst substrate; an inner pipe provided at the case inside the outer pipe, an axial direction end portion of the inner pipe being formed in a tapered shape and a distal end face of the axial direction end portion being formed in a curved surface shape; and an insulating layer provided at least at an inner side face and the axial direction end portion of the inner pipe.

Abstract: A vehicle is equipped with an internal combustion engine, and an exhaust pipe of the internal combustion engine is supported on a vehicle body by a plurality of support members. A support member positioned on the mostdownstream side of the exhaust pipe, among the plurality of the support members, is a buffer member functioning as a resonance suppression mechanism that suppresses the resonance of the exhaust pipe.

Abstract: A liquid sealed-in vibration damper respectively connected with two members that perform a relative displacement includes an elastic member, which is provided therein with a liquid chamber in which a liquid is sealed. When a direction from a side of the liquid sealed-in vibration damper connected with one of the two members to a side of the liquid sealed-in vibration damper connected with the other of the two members is set to an extension direction of the elastic member, a recess is provided in a region between an end portion on a side of the elastic member connected with any one of the two members and the liquid chamber, the recess being recessed in a direction orthogonal to the extension direction up to a position where a position of the recess in the orthogonal direction is located at an inner side of the liquid chamber.

Abstract: In an exhaust pipe structure, there are provided a first supporting member that is attached to an exhaust pipe or a component attached to the exhaust pipe; a second supporting member that is attached to a vehicle body or a component fixed to the vehicle body; a supporting rubber member that connects the first supporting member to the second supporting member; and a reaching-prevention member that contacts the supporting rubber member just before the supporting rubber member reaches the supporting rubber member sticking position.

Abstract: In an exhaust pipe structure (10), there are provided a first supporting member (20) that is attached to an exhaust pipe or a component (60) attached to the exhaust pipe; a second supporting member (30) that is attached to a vehicle body or a component (70) fixed to the vehicle body; a supporting rubber member (40) that connects the first supporting member (20) to the second supporting member (30); and a reaching-prevention member (50) that contacts the supporting rubber member (40) just before the supporting rubber member (40) reaches the supporting rubber member sticking position.

Abstract: An exhaust pipe connecting device includes a seal member, mounted on an end portion of a first exhaust pipe; a coupling member, mounted on an end portion of a second exhaust pipe; and a spring member, provided between the first exhaust pipe and the second exhaust pipe, that presses the seal member toward the coupling member. The first exhaust pipe and the second exhaust pipe are rotatably connected to each other while the coupling member contacts the seal member. The spring member has nonlinear spring characteristics such that a spring constant in a high load region in the operation range of the spring member is larger than a spring constant in a low load region in the operation range of the spring member.
