An assembly unit 1 of an exhaust system has at least one and particularly two connection funnels 2 made of cast material and a pipe 3. The at least one connection funnel 2 has a pipe socket 21 and at least one bracket 22. The bracket 22 is arranged outside of the pipe socket 21. A connection section 31 of the pipe 3 is fastened to the bracket 22 of the at least one connection funnel. The pipe socket 21 extends beyond the connection section 31 of the pipe 3 into the interior of the pipe 3 and is spaced apart from an inner wall of the pipe 3 by at least the simple wall thickness of the pipe 3.

The present invention relates to a tail trim assembly of an exhaust pipe for a vehicle of which shape is simplified to reduce the number of portions and process is changed to simplify processes so that manufacturing cost is reduced and productivity and quality are improved, and a method of manufacturing the tail trim. According to the present invention, a tail trim of an exhaust pipe for a vehicle includes a first tail trim portion of which one end is attached to an exhaust pipe at the rear portion of a vehicle, and a second tail trim portion that has an inner diameter increased in a streamlined shape toward the outside and is integrally formed with the other end of the first tail trim portion.

A high-Cr, high-Ni, heat-resistant, austenitic cast steel comprises as main components C, Si, Mn, Cr, Ni, W and/or Mo, and Nb, the balance being substantially Fe and inevitable impurities, N being 0.01-0.5%, Al being 0.23% or less, and O being 0.07% or less by weight. Exhaust equipment members are produced by using this high-Cr, high-Ni, heat-resistant, austenitic cast steel.

The invention relates to a double-walled exhaust manifold (10) for a motor vehicle, said exhaust manifold comprising at least one inner element (12) provided with sliding tubes (16, 18) which fit into each other, and an outer element (14) which is moulded from a single piece around the inner element (12) with which it determines an inner insulation cavity (20). The inventive exhaust manifold is characterised in that the inner element comprises at least one first straight upstream tube (22), a first end (24) of said tube being arranged in the extension of an exhaust line of an associated heat engine cylinder head and a second end (26) fitting together, in a sliding manners with an intermediate part (28) of at least one downstream tube (16, 18) having an axis (B) intersecting the axis (A) of the first tube (22).
摘要:
A muffler having a muffler body divided into first and second exhaust chambers by a partitioning member which has a third exhaust chamber formed therein. An exhaust inlet introduces exhaust gas from an engine into the first exhaust chamber. First communication bores provide communication between the first and second exhaust chambers, and second communication bores provide communication between the second exhaust chamber and the third exhaust chamber. The third exhaust chamber is open to the atmosphere through an exhaust outlet pipe. An exhaust emission control catalyst is carried on an outer surface of the partitioning member facing the first and second exhaust chambers, as well as on an inner surface of the partitioning member facing the third exhaust chamber. An inner surface of the muffler body does not carry the exhaust emission control catalyst.

A method of fabricating a catalyst converter includes the steps of: obtaining a tubular member by rolling up a metallic plate member of a rectangular shape having ear portions at four corners thereof such that opposing ones of the ear portions abut against each other, and by effecting butt welding for both ends of the plate member; cutting off projecting portions formed by the ear portions at both ends of a weld of the tubular member; incorporating a catalyst carrier into the tubular member with the projecting portions cut off; effecting drawing for both end portions of the tubular member with the catalyst carrier incorporated therein; and attaching a pair of flanges, respectively, to the both end portions of the tubular member subjected to drawing.

A cast iron exhaust manifold having an inside surface covered with a ceramic coating comprising, by weight, about 30% to about 70% unfused silica, about 5% to about 30% magnesia, about 5% to about 20% alumina and about 3% to about 10% sodium oxide. The coating will preferably be built up in multiple layers at least one of which is relatively porous and another is relatively dense resulting from vacuum degassing of the slurry used to deposit the coating.
