In the present embodiment, carrier 409 is the frustum of a cone structure, promptly the circular inner diameter of drum 405 by end portion 406 towards drum 405 in contrast to end portion another openend 410 convergents of 406.At openend 410 places, carrier 409 is preferably strengthened around the ring 411 of longitudinal axes L with one heart by one, that is this ring 411 410 places define a circular open that is used for drum 405 in the end.
410 place's drums 405 extend into an ancillary chamber 412 in the end, and this ancillary chamber is formed at the inner surface of end wall 403, and extend in 410 zones, end around the drum 405, and it only is the part of drum total axial length along development length.Ancillary chamber 412 stretches out, communicates in order to the tubular configured joint 413 of feeding fresh air from housing 410 with one.Aspect this, fresh air can be provided by the fan that also is connected in electro-motor 408 in addition, perhaps in the end 410 of drum 405 suitable turbo blade is set, in order to replenish fresh air.This layout means that the oxygen content of emission gases can increase, thereby can obtain sufficient oxygen in the catalytic substance place, so that the harmful side product in the engine exhaust gas is transformed fully.So just for example can eliminate expensive motor λ control.This CC Catalytic Converter is particularly suitable for being assembled to because of being equipped with on the motor vehicles of non-adjustable type CC Catalytic Converter in that electronics λ regulating system (for example because it be a carburetor engine) can't be installed on the engine.
In addition, this catalyst device can directly be arranged in the motor space behind the engine, and need not worry that CC Catalytic Converter is overheated, because emission gases is in fact in any case all can be by the feeding of fresh air and cool off.
One tubular portion 415 passes through end wall 403 with sealing relationship.This tubular portion 415 and the coaxial setting of longitudinal axes L, its openend that extends in the cavity 405 ' of drum 405 are the intervals and end portion 406 adjacent settings with a part that equally only constitutes drum 405 total axial lengths.On the other hand, the other end that tubular portion 415 has opening equally outwards passes through end wall 403 with sealing relationship, and the discharge gas after will purifying is disposed to as the conventional exhaust device.Be provided with a joint 418 being parallel to wall 414 and keeping with it at interval wall 417, be fed to cavity 402 parts of surrounding drum from the last purifying exhaust gas (as shown by arrow B) of engine.As shown in the figure, in the embodiment shown, joint 418 is to arrange like this, that is: the direction of axis L longitudinally is near end wall 403, keep clear of end wall 404, therefore, near drum 405 almost along being formed at the end 410 of end wall 403 with the whole length extension of 404 cavity 402, keep clear of end portion 406, in other words, joint 418 that a part of drum 405 zones little that are diameters of being positioned at drum than end portion 406.In addition, joint 418 is with respect to the central plane M that comprises longitudinal axes L and extend perpendicular to wall 414 and end wall 417 and horizontally set, makes to discharge gas and almost feed in the cavity 402 with the tangential direction with respect to drum 405, as arrow B among Fig. 8 ' shown in.In illustrated embodiment, joint 418 is that the next-door neighbour is provided with one of in the two side 419 and 420, and described sidewall is all perpendicular to end wall 403 and 404, also perpendicular to wall 414 and 417.
Especially as shown in Figure 8, housing 401 forms an inner space or a cavity 403 corresponding to shell structure, and it also is cube or parallelepiped, but is non-circular cross section on the cross section perpendicular to longitudinal axes L especially, is specially square in this embodiment.This cross sectional shape make when drum 405 when longitudinal axes L is rotated, in cavity 402 parts of encirclement drum 405, can't form air with the certain volume of drum rotation.Therefore that is form damping (chicane or the baffle) configuration of avoiding this air to move therefore, this square sectional stops the air that forms the certain volume that rotates with drum.
If housing is rectangle cross section or triangular-section or corresponding polygonal cross section,, then can realize same effect as hexagon.
Also can further provide other damping to arrange, for example be projected to the form of cavity 402 for rib for example, strip or tabular 422 in enclosure interior.
Fig. 8 shows the another embodiment of catalyst device of the present invention.In this example, the discharge gas of engine enters the inner space or the cavity of housing 427 from an inlet tube 423, as shown by arrows.The catalyst carrier that is provided with in housing, in this example, it also is the form of drum 425, yet is a cylindrical shape in the embodiment shown.This drum is at its end seal closure in contrast to feeding joint 423, and is provided with a rotor 432.Also be provided with a guide wheel or impeller 431 at rotor 432 and 423 of joints.Another end wall in contrast to this end has a concentric opening, and by therebetween, this outlet 424 communicates with the discharge gas system of using always (preposition muffler and rearmounted muffler) outlet 424 then with sealing relationship.Drum 425 utilizes suitable installation configuration 429 to be rotatably installed on the outlet 424, configuration 429 wherein is installed also makes drum 425 inside with respect to these housing 427 inner sealings.
Figure 10 is the cutaway view that passes Fig. 9, and this cutaway view shows the back of guiding or drives impeller 431.The rotating shaft 428 and the inlet attack 423 of drum 425 can be seen in this.Simultaneously, obviously housing 427 is a square sectional, and the wheel 431 of same size all extends to corresponding housing wall with rotor ring 432 on the drum 423.
Especially as shown in Figure 9, the diameter of drum 425 is less than the diameter of rotor 432.On the contrary, this diameter is corresponding to the internal diameter of rotor ring.As a result, as shown by arrows, from the discharge gas of the engine inlet attack 423 of flowing through, guide wheel or impeller 431 and rotor ring 432 enter the inner space or the cavity of rotor ring 432 back casings 427.Thus, discharge gas is driven the drum 425 through quick rotation.The quick rotation of this drum and drum comprise that preferably position that the fact of multilayer details shape net decorations makes that the catalyst of contained pollutant transforms in the emission gases occurs in the minimum space.Discharge gas after this purifies flows in the cavity of drum 425, and mat discharge tube 424 enters in the usual drainage facility thus.Under the situation of this example, after being adapted at CC Catalytic Converter of the present invention and non-traditional cellular CC Catalytic Converter is assembled on the existing motor vehicles.Particularly do not need vehicle is done any change, especially do not need to provide and drive electronic being electrically connected.
Figure 11 shows the another of catalyst device used carrier of the present invention may embodiment.In this example, the inner core 436 of drum 435 comprises a grid member, for example the V2A net.It is surrounded as ceramic material by an insulant 437.At last, the catalyst carrier 439 of insulant 437 portability reality, it comprises the sieve shape woven wire that is coated with catalytic substance.
