摘要： A catalyst support for an exhaust gas purifier having a cylindrical, ceramic substrate with a helical groove on the periphery of the substrate and being contained within a cylindrical casing having a radially outward helical channel complimentarily aligned with the helical groove of the substrate, such that the helical groove and helical channel define a helical conduit between the casing and the substrate. A compressible wire mesh rope of cross-sectional area slightly larger than the cross sectional area of the helical conduit is compressed within the helical conduit along substantially the entire length of the helical conduit to apply a radial pressure on the substrate periphery, thereby fixing the position of the substrate while allowing thermal expansion of the substrate into an annular space between the casing and the substrate.

摘要： The inlet opening of a chamber is connected to the exhaust manifold of an internal combustion engine so that the combustion products pass through the chamber to an exit opening. The chamber contains a pair of baskets which are open at their upstream ends and closed at their downstream ends. The sides of the baskets are made up of thin copper wire strands placed side by side. The exhaust from the engine is brought into the first basket and the pulses of pressure from the engine exhaust bows the wires outward in a pulsating manner to alternately open and close the spaces between the wires allowing the gases to pass through the spaces. Atmospheric air is introduced into the first basket to mix with the combustion products. The gases emanating from the first basket are introduced into the open end of the second basket and pass through the walls of the second basket in the same manner as the first basket, and then on to the exhaust opening. A feedback conduit leading from the area between the two baskets is brought to the carburetor to feed a minor part of the products within the chamber to the carburetor air inlet opening. Blue sparks are provided at the region of the chamber between the two baskets and also at the carburetor inlet opening. The effect of the small pieces or finely divided copper and the sparks is to produce chemical reactions which result in nearly eliminating from the exhaust opening from the chamber, unburned hydrocarbons, nitrogen oxides and carbon monoxide.

摘要： The present form of direct flame incinerator unit makes use of heat exchange tubing in two different, end-to-end heat exchange sections. Large diameter, self-supporting tubes are used to surround the flame-combustion zone and eliminates the conventional use of an expensive, interior cylinder positioned within and around the flame zone so as to separate the incoming gas stream from the combustion product stream. A multiplicity of small diameter tubes are used in the downstream part of the unit, with respect to combustion gas flow, and these tubes connect through a redistribution section to the larger diameter tubes around the flame-combustion section, whereby the incoming gas stream passes entirely countercurrently to the combustion gases and feeds directly into a plenum section around the burner means.

摘要： An air-pollution preventive arrangement for use with an internal combustion engine for motor vehicles, adapted to reduce the concentrations of noxious compounds such as unburned hydrocarbons and carbon-monoxides contained in the engine exhaust gases. The arrangement comprises a thermal reactor for primarily recombusting the exhaust gases and a catalytic converter for secondarily recombusting the exhaust gases passed from the thermal reactor so as to oxidize the residual unburned compounds. An air injection unit supplies additional air which is admixed, in a limited proportion, to the exhaust gases entering the thermal reactor to aid in the primary re-combustion of the exhaust gases therein. The noxious unconsumed hydrocarbons and carbon-monoxides are thus converted into innocuous compounds at efficiencies which are far higher than those attained where the thermal reactor or the catalytic converter is employed independently. Such additional air may also be admixed to the exhaust gases entering the catalytic converter which is located downstream of the thermal reactor, whereby the re-combustion efficiencies of the reactor and converter are maintained athigh levels throughout varying driving conditions of the motor vehicle. The arrangement may also comprise a second catalytic converter which is adapted to reduce nitrogen oxides in the exhaust gases.

摘要翻译： 适用于汽车内燃机的空气污染预防措施，适用于减少发动机废气中所含的有害化合物如未燃碳氢化合物和一氧化碳的浓度。 该装置包括用于主要再燃烧废气的热反应器和用于二次重新排放从热反应器通过的排气的催化转化器，以便氧化剩余的未燃烧的化合物。 空气注入单元提供额外的空气，其以有限的比例混入进入热反应器的废气以帮助其中的废气的初次再燃。 因此，有毒的未消耗的碳氢化合物和一氧化碳被转化为无害化合物，其效率远高于单独使用热反应器或催化转化器所达到的效率。 这种附加空气也可以混入进入位于热反应器下游的催化转化器的废气，由此在机动车辆的变化的驾驶条件下，反应器和转化器的再燃烧效率保持在高度水平。 该装置还可以包括适于减少废气中的氮氧化物的第二催化转化器。

摘要： A catalytic exhaust purifier for diesel engines has a housing with means forming an inlet opening substantially centrally in one end of the housing and means forming an outlet opening substantially centrally in the other end of the housing. Within the housing there is a hollow cylindrical catalyst bed having a pair of opposed end walls, inner and outer spaced cylindrical grids secured to said end walls and oxidation catalyst pellets disposed between said grids. One bed end wall is secured to the inlet end of the housing and has a central opening communicating with the inlet opening in the housing. The other bed end wall is spaced from the other end of the housing and the outer cylindrical grid is spaced from the interior of the housing to provide a path for the flow of gas from the outer grid to the outlet opening of the housing. Support members spaced to provide for the passage of gas are fixedly secured to the bed end wall adjacent the outlet opening in the housing and slidably engage the means forming said outlet opening to support the catalyst bed and accommodate the longitudinal expansion and the contraction of the catalyst bed incident to temperature changes.
