摘要： The converter casing includes a hollow cylindrical body in which a monolithic catalyst substrate is supported by a wire-mesh cushioning element. Secured to the casing body are a pair of holding fixtures which are each fitted with an end cushioning element engageable with the adjacent end face of the catalyst substrate to hold the latter against axial displacement. The casing body includes a smaller-diameter portion, at least one larger-diameter portion and a sloped shoulder portion interposed therebetween. The holding fixtures are fixed to the larger-diameter or other end portions of the casing body in spaced relation to the cushioning element held between the catalyst substrate and the casing body. Such casing structure reduces the danger of the catalyst substrate being damaged or broken under vibration or shock to a minimum thereby to enhance the durability of the substrate and enables realization of a particularly compact and inexpensive catalytic converter.
摘要翻译：转换器壳体包括中空圆柱体，其中整体式催化剂基底由丝网缓冲元件支撑。固定在壳体上的是一对保持固定装置，每个保持固定装置都配有可与催化剂基板的相邻端面相接合的端部缓冲元件，以使其抵抗轴向位移。壳体包括较小直径部分，至少一个较大直径部分和插入其间的倾斜肩部部分。保持固定装置与保持在催化剂基板和壳体之间的缓冲元件间隔开地固定到壳体主体的较大直径或其它端部。这种壳体结构减少了催化剂基板在振动或冲击下损坏或破坏的危险，从而提高了基板的耐用性，并且使得能够实现特别紧凑且便宜的催化转化器。

摘要： A system for collecting and catalytically cleaning exhaust gases from an engine which is particularly suited for an arrangement wherein the catalyst is in close proximity to the exhaust ports of the engine. Exhaust pipes are employed having common walls extending longitudinally therethrough to separate and convey exhaust gases from two separate cylinders to a common manifold. The manifold is arranged to provide a mixing of the exhaust from a plurality of cylinders and to direct that homogeneous flow to the catalyst. A restriction is provided at the outlet of the manifold chamber and before an expansion chamber into the catalyst. This outlet and the expansion chamber are designed to provide maximum efficiency in distribution of gases to the catalyst and also provide minimum gas flow disruption and back pressure.

摘要： Separate exhaust pipes each receive exhaust gases from a plurality of cylinders of an internal combustion engine. The exhaust pipes merge into a common outlet delivering exhaust gases into a first reaction chamber and then into a second reaction chamber enclosing the first reaction chamber. The second reaction chamber also encloses the exhaust pipes and outlet. The cross section areas of the exhaust pipes, outlet and continuing passageway through the first reaction chamber are substantially the same in effective cross section area to avoid temperature drop in the exhaust gases due to expansion. Oxygen-rich exhaust gases from the engine are held at a high temperature for long residence time to oxidize HC and CO and thereby minimize the quantity of these pollutants discharged into the atmosphere.

摘要： An exhaust manifold for a multi-cylinder internal combustion engine is provided with preliminary oxidation reaction chambers, each of which receives exhaust gases from exhaust port liners each serving a pair of adjacent cylinders of different exhaust timing. These preliminary oxidation reaction chambers each communicate downstream with a main oxidation reaction chamber subdivided into a plurality of concentric subchambers. The subchambers enclose the preliminary oxidation reaction chambers and exhaust gas inlet pipes. Combustion of unburned hydrocarbons (HC) is principally accomplished in the preliminary oxidation reaction chambers, and the exhaust gases are maintained at relatively high temperature and retained for a sufficient period of time in the subchambers to accomplish oxidation of the unburned carbon monoxide (CO).

摘要： An exhaust purifying system for a multi-cylinder four-cycle internal combustion engine operating on an intake mixture leaner than stoichiometric employs first preliminary reaction chambers receiving exhaust gases from ports connected to cylinders having successive firing order. The exhaust gases are then delivered from said first preliminary reaction chambers to a single second preliminary reaction chamber and then to a catalytic reaction chamber containing oxidative catalysts of base metals, and then finally to an oxidative reaction chamber. The intake mixture for the engine is heated from exhaust gases in the oxidative reaction chamber. This particular succession of chambers causes the temperature of the exhaust gases to increase to above 800.degree. C.

摘要： An exhaust manifold for a multi-cylinder engine employs three concentric exhaust reaction chambers. Exhaust inlet pipes convey hot exhaust gases from the exhaust ports of the engine directly into the innermost reaction chamber. The concentric reaction chambers extend substantially at right angles to the exhaust inlet pipes which are parallel. Concentric tubes encircle the exhaust inlet pipes and each is connected to one of the concentric exhaust chambers. The flared portions of the exhaust inlet pipes engage in surface contact with the correspondingly flared portions of the tubes. End members having concentric shoulders engage cylindrical shells which define the exhaust reaction chambers. Bolted spacers are positioned substantially midway of the length of the shells and space them in concentric fashion.

摘要： An exhaust reaction chamber assembly is provided for a four-cylinder in-line internal combustion engine having two pairs of exhaust ports, the ports in each pair being closely spaced. The assembly includes an exhaust manifold having two preliminary reaction chambers each connected to receive exhaust gases from one of said pairs of exhaust ports, respectively. A main reaction chamber is provided within the exhaust manifold and two curved passages each connect one of the preliminary reaction chambers to the main reaction chamber, respectively, each passage curving for about 90.degree.. The passages have aligned outlets so that the exhaust gases from each passage are directed toward the other passage. The gases are then directed perpendicular to the inlet in an elongated direction through the main reaction chamber. In one embodiment, the aligned outlets are spaced apart within the main reaction chamber, and in a modification the aligned outlets are formed in a single pipe having a side window opening into the main reaction chamber. A restriction may be placed between each passage and the preliminary reaction chamber to which it is connected, in order to increase residence time.
