Thermal protection joint for exhaust line of supercharged oil engine, has central part made of thermal conductive material, and peripheral part made of thermal insulating material realized in mica and extending along exterior edge of joint

摘要

The joint (40) has an exterior peripheral edge (49), and an interior edge (48) that defines a central opening (43) with a diameter (D1) in a range of 8 to 12 millimeters. A central part (42) is made of a thermal conductive material realized in an alloy comprising copper, and extends along the interior edge. A peripheral part (41) is made of a thermal insulating material realized in mica, and extends along the exterior peripheral edge, where the materials are gas-sealed. The central part includes a width (D2) in the range of 1 to 3 centimeters. An independent claim is also included for an exhaust line of an internal combustion engine comprising an exhaust conduit.
