Definitions

  • This invention relates to a device for the subsequent combustion of fuel ingredients and refers more particularly to a device for a catalytic subsequent combustion of unburned or partly burned :fuel ingredients in the exhaust of internal combustion engines. y
  • An object of the present invention is the provision o-f a device which will eliminate the drawbacks of prior art constructions and which will comply with operational requirements both from a heat technical as well as a manufacturing point of View.
  • Another object is the provision of a device, the construction o-f which take-s into consideration thefact that subsequent combustion results in high temperature of about 900 C. and more, whereby these high temperatures require a free expansion possibility of the device carrying the catalystwithin a casi-ng ⁇ subjected to .gas llowy and constructed, by way of example, as a muffler.
  • the objects of the present invention may be realized substantially through the provision of a device wherein the catalyst ,carrier located in a casing preferably constructcd as a muii'ter, is firmly connected with a casing solely, or substantially solely in one transverse plane and beside this connection, on all other sides is surrounded by the exhaust gases, whereby the carrier is supported so that it is shiftable :in its longitudinal direction.
  • the catalyst carrier so to say, floats in the casing which eri-closes it and which, by way of example, is constructed as a mutiler.
  • Such arrangement in accordance with the present invention provides not only a completely free heat expansion of the catalyst carrier but also assures an excellent heat insulation of the catalyst carrier in relation to the medium of the surrounding casing.
  • the catalyst carrier is preferably suspended in the casing at its two front sides, particularly so that it is firmly connected with the casing at the side of the gas outlet and is movably connected with the casing by means of a gas iniiow pipe upon the side of the gas inlet.
  • a further advantage of the invention consists in the possibility of easily and conveniently removing the catalystl carrier out of the casing and rte-introducing it therein, in that the catalyst carrier is movable in and out, fo1 example, in the manner of a drawer of a chest of drawers.
  • the catalyst carrie-r supported for longitudinal movement includes preferably an ante-chamber into which is guided an exhaust inflow pipe serving preferably as a movable support and extending through the catalyst chamber.
  • the catalyst carrier or the catalyst chamber can ibe strengthened by longitudinal walls.
  • a transverse pivot is preferably used for attaching the catalyst carrier to a special removable closing wall of the muffler casing, whereby the pivot extends through openings of supports provided in the catalyst carrier or simultaneously provided in a pot-like cover closing the catalyst chamber,
  • This constnuction has the advantage that when the closing :wall is removed, the catalyst carrier can be removed with it out of the casing by means of the transverse pivot, whereby after removing the pivot and taking oif the cover, the interior of the catalyst chamber becomes easily accessible from the outside.
  • the casing enclosing the catalyst carrier can be constructed as anv absorption 'mutlien in that thewalls of ⁇ the casing may consist, for example, of perforated sheet metal and the catalyst carrier may be surrounded by an absorbing substance, preferably stone wool.
  • the device of the present invention is suitable for al types of machines. However, it is of particular importance for two-stroke motors, particularly in combination with gas-dynamic scavenging, the so-called resonance charging.
  • the preliminary mufller positioned as a resonance charger can be combined with the device of the present invention into a singleunit, or may be located in front of the device as an independent unit.
  • FIGURE l is partly a side view of and partly a longitudinal section along the line 1-'1 of FIG. 2 througha nruier provided with a catalyst carrier constructed in accordance with Vthe present invention.
  • FIGURE y2 is partly a top view of and partly a longitudinal section along the :line 2-2 of FIG. 1.
  • FIGURE 3 is a sectional view of a portion of the device enclosed by the lines 3 in FIG. 1 on an enlarged scale.
  • FIGURE 4 is a sectional view of the portion ofthe device enclosed by the lines 4 in FIG. 2 on an enlarged scale.
  • FIGURE 5 is a transverse section along the line 5-5 y of FIG. l-on an enlarged scale.
  • FIGURES 6 and 7 are two transverse sectional views similar to FIG. 5 but illustrating other embodiments of th present invention.
  • Thedevice illustrated in FIGS. 1 to 5 includes the muboardr casing 10 rwhich lloatingly supports a catalyst carrier 11 in a manner which will be described in greater detail hereinafter, whereby one end of the catalyst carrier is immovably connected with a closing wall ⁇ 13 which is removably attached by screws 12 to the muffler casing 10, and whereby the other end of the catalyst carrier 11 is movably supported in an intermediate wall or separating wall 14 of the muffler casing 10.
  • the catalyst carrier 11 consists essentially of a catalyst chamber 15 which is filled by catalyst particles and which, in the example illustrated, is divided into three individual cha-mbers 15a, 15b and 15C, as well as an ante-chamber 16 which receives the gases before they enter into the catalyst chamber 15.
  • the catalyst chamber 15 is formed of two longitudinal side walls 17a and 17b, intermediate supporting walls 18a and 18h, which in the example illustrated, are provided with large openings, as well as sieve surfaces 19 and 20.
  • a cover-like sheet metal wall 21 which closes the ante-chamber 16 from the outside, is connected with the Walls of the chamber 15, for example, in such manner that the edges of the sieve-like metal sheets 19 are held between the sheets 17a or 17b and the sheet 21.
  • the metal sheets 17a, y17b, 18u, 18b, 19, 20 and 21 are further joined, preferably by soldering, with the end walls 22 and 23 to constitute the catalyst carrier, whereby the rear ends of the sheet metal walls 19 and 20 are extended at their rear ends at 24a and 24h, and these extensions are engaged by a potlike cover 25 which is elongated in the transverse direction and which is U-shaped in crosssection.
  • a bent tube 26 for the iniiow of exhaust is yfirmly mounted in the front end wall 22 of the catalyst carrier 11 and is firmly connected with the wall 22 or the sievelike metal sheets 19, or other parts of the catalyst carrier 11, preferably by soldering.
  • the exhaust inflow pipe 26 opens with its sidewise bent rear end 27 into the ante-chamber 16, while its front end 2S is supported in an axially movable manner in a pipe socket 29 carried by the intermediate wall 14.
  • the front end of the socket 29 receives an extension pipe 3'1 projecting into the entry chamber 3i) of the mutiier.
  • the pipe .31 can also extend into the exhaust inflow pipe 26.
  • the catalyst carrier generally designated as 11, is iloatingly supported within the muiiier casing 19 and is enclosed by a chamber 32 which receives the exhaust gases after they have passed through the catalyst chamber, whereupon the exhaust gases escape to the outside air through the rear gas outtiow pipe 33.
  • a ⁇ tubular pivot 34 is used to connect the catalyst car'- ⁇ rier 11 with the removable closing Iwall 13 of the muier .casing y10. As shown in FIG. 4, ⁇ the pivot 34 extends through openings of end walls 35a and 35b of the potlike cover 25, the supports 37a and 37b of the catalyst carrier 11 and furthermore, the supports 38a and 38b of the closing Wall 13. l g g Furthermore, in the example shown in FIGS. l to 5, the entire muftier or a larger part thereof, is enclosed by a cover 39 which surrounds and is spaced from the walls of the muliier casing 1t), whereby the intermediate space 40 between the casing 1t) and the cover 39 is filled with a sound absorber, preferably stone wool.
  • the walls of the muiiier casing within the enclosure of the cover can be made of perforated sheet metal, if desired.
  • Exhaust .gases arriving from the motor reach the entry chamber 30 of the muffler whereby they are dammed at the separation wall and pass through the intermediate pipe 31 and the bent pipe 26 into the ante-chamber'16 which extends substantially along the entire length of the catalyst carrier to the side of the catalyst chamber.
  • the exhaust gases extend comparatively uniformly throughout the length of the antechamber 16 and pass into the catalyst chamber 15, namely, into the individual chambers a, 15b and 15e thereof, whereby after passn ing through the sieve-like metal sheets 19, they come in intimate contact with the catalyst particlesso that the unburned parts of the exhaust gases are now burned.
  • the exhaust gases flow out of the catalyst chamber 15 through the sieve-like metal sheets into the outer chamber 32 serving as the exit space of the muffler,
  • the exhaust inflow pipe 26 can slide in the pipe socket 29 of the muiiier. Since the catalyst carrier 11 is enclosed on all sides by the exhaust gases located in the outer chamber 32, and Since its metal sheet walls are completely separated from the wall of the mufiier casing 10, there is no friction or clamping of the catalyst carrier in the muiiier casing and the catalyst carrier is most effectively insulated from outer heat losses.
  • the operator unscrews the screws 12 and then removes the closing wall 13 along with the outflow pipe 33 from the muflier casing, whereby, due to the provision of the transverse pivot 24, the entire catalyst carrier 11 will be removed yalong with the closing wall 13. The operator then pulls out the transverse pivot 34 so that the catalyst carrier 11 will be separated from the closing wall 13. Then the operator removes the pot-like cover 25.. Then the interior of the catalyst chamber 15 is freely accessible from the outside.
  • the supports 38a and 38!) are advantageously so shaped that they, -with the possible addition of inserts, engage the pot-like cover 25 to secure the catalyst carrier against turning about the axis of the transverse pivot.
  • the insertion of the catalyst carrier 11 and the insertion of the exhaust inlet pipe 26 into the pipe socket 2d of the muiiier is carried out without any difhcultics.
  • FiG. 6i differs from the device hereinbefore described, in that the catalyst carrier is Aformed by a sheet metal tank 41 which is U-shaped in cross-section.
  • the sieve-like metal sheets 19 and 20 and the intermediate longitudinal walls 15a and 13b are introduced Vinto the tank 41.
  • the tank 41 contains the ante-chamber 16 as well as the ⁇ catalyst chamber 1 5.
