摘要： An exhaust manifold includes a body portion and a flange portion. The body portion includes a first split body having a plurality of semi-cylindrical portions, and a second split body having a plurality of semi-cylindrical portions. The semi-cylindrical portions of the first and second split bodies overlie each other, respectively, and define branch pipes. The exhaust manifold includes a first weld bead and a plurality of second weld beads. The first weld bead welds the semi-cylindrical portions defining one of the branch pipes to each other from an outer surface side. The second weld beads weld an outer peripheral portion of the one of the branch pipes to an edge portion of opening in the flange portion. At least one of the second weld beads partially overlaps the first weld bead. End portions of neighboring second weld beads overlap each other and are separated from the first weld bead.

摘要： An apparatus comprises a housing comprising a housing first portion and a housing second portion. The housing first portion comprises a first joint portion overlapping a second joint portion of the housing second portion so as to form a housing joint. A clamp is positioned on the housing joint and comprises a base portion. A first surface of the base portion is positioned on the housing joint. A plurality of legs extend from the base portion towards the housing each of which are spaced from each other around the housing joint. A plurality of flange segments extend from each side of the base portion away from the housing. A band is positioned on a second surface of the base portion opposite the first surface and around the clamp. The band is positioned between the plurality of flange segments and operatively coupled to the housing via the clamp.

摘要： A fluid-conduit collector (20, 20.x, 20a, 20b) spans across a plurality of collector-inlet interface structures (24, 24.1, 24.2, 24.3, 24′, 24″) and at least one fluidic diode element (26, 26.1, 26.2, 26.3, 26′, 26″). A branch inlet portion (20′″, 20.1′″, 20.2′″, 20.3′″) of at least one collector-inlet interface structure (24, 24.1, 24.2, 24.3, 24′, 24″), in fluid communication with a corresponding fluid-conduit runner portion (14, 14.x), provides for receiving fluid from a source of fluid (12). A main inlet portion (20.x′) of the collector-inlet interface structure in fluid communication with an outlet portion (20.x″) thereof defines a portion of the fluid conduit of the collector 20, 20.x, 20a 20b). The branch inlet to on 20′″, 20.1′″, 20.2′″, 203′″) is in fluid communication with the outlet portion (20.x″) via a collector inlet port (56′, 106) that is at least partially bounded by a relatively sharp-edged junction (60) with the fluid conduit of the collector (20. 20.x, 20a, 20b). The fluidic-diode element (26, 26.1, 26.2, 26.3, 26′, 26″) located coincident with, or downstream of, the collector inlet port (56′, 106) provides for a relatively higher coefficient of discharge for fluid flowing (34, 64) towards (36) an outlet (38) of the collector (20, 20.x, 20a, 20b), than for fluid flowing (32) in a reverse direction (40).

摘要： The present invention relates to an automobile urea tank and a forming method thereof. The method includes the following steps: 1) producing an upper half casing and a lower half casing through an injection molding method; 2) after the upper half casing and the lower half casing are formed, assembling built-in parts of the upper half casing and the lower half casing; 3) welding the assembled upper half casing and the assembled lower half casing to form a whole; and 4) assembling components on surfaces of the upper half casing and the lower half casing. This method can improve design freedom of built-in elements of the tank body, and can save a lot of raw materials; the structure is simple and firm; moreover, the production efficiency is improved, and the production cycle is shortened.

摘要： An exhaust manifold for installation onto a cylinder head of an internal combustion engine includes a housing having plural inlet openings and an outlet opening. The housing includes an inner shell and an outer shell in surrounding relationship to the inner shell to define a gap there between. The inner shell is floatingly arranged in the outer shell and rests at a side of the cylinder head upon a guide plate which is formed with the plural inlet openings and includes guide members respectively arranged about a circumference of the inlet openings. The outer shell has a cylinder-head-proximal marginal region formed with an outwardly bent flange that rests upon the guide plate and is joined in gastight manner to the guide plate by a material joint. The flange has an outer side in opposition to the guide plate, with a collar being arranged on the outer side of the flange.
