Definitions

  • the invention relates to an exhaust-gas system for a motor vehicle, comprising at least one exhaust-gas cleaning system and at least one regeneration device for the exhaust-gas cleaning system, by means of which regeneration device an oxidizable fluid can be introduced into the exhaust-gas stream ahead of the exhaust-gas cleaning system, the regeneration device comprising a housing with a chamber formed in it as well as a heating element positioned in the chamber.
  • Exhaust-gas cleaning systems in the sense of the invention may include, in particular, diesel particle filters and NO x -storage catalytic converters.
  • suitable particle filters are employed for reducing the particle-shaped emissions of diesel motor vehicles.
  • particle filters have to be regenerated from time to time through burning off the particles which have accumulated on the filter surface.
  • an oxidation-based catalytic converter is usually arranged upstream of the diesel particle filter, which through oxidation of an oxidizable substance in the exhaust-gas stream produces the heat which is needed for burning off the diesel soot particles.
  • NO x -storage catalytic converters are increasingly used, which serve for reducing the nitric-oxide emission.
  • special measures are required in particular in the case of diesel engines which run with an excess of air and whose exhaust-gas likewise has an air surplus.
  • the invention provides an exhaust-gas system with a regeneration device which compared to the systems known from prior art provides for a more uniform distribution of the oxidizable fluid and at the same time needs a smaller amount of electric energy.
  • the housing has on its upstream side an inflow opening for exhaust gases and on its downstream side an outlet opening and is arranged in the interior of the exhaust-gas stream.
  • the exhaust-gas system according to the invention possesses a regeneration device which is arranged within an exhaust-gas carrying tube and through which a part of the exhaust-gas flows.
  • an injection nozzle for the oxidizable fluid which sprays the fluid in the direction of the exhaust-gas stream onto the heating element.
  • the arrangement of the regeneration device in the interior of the exhaust-gas stream offers the advantage here that the heating element is heated not only by electric energy, but in addition by the exhaust-gases flowing through the chamber of the regeneration device. Thereby the energy is reduced which is required for vaporizing the fluid.
  • the exhaust-gases flowing through the housing help to transport the fluid through the heating element.
  • the configuration according to the invention is distinguished in that a more complete vaporization is achieved in the chamber by the protecting housing.
  • the housing preferably has an essentially tubular shape with a tapered upstream end. In this way it is achieved that merely a small part of the available exhaust-gas flows through the housing, which furthermore has a comparably small resistance to flow. What is more, due to the continuous widening of the housing in the direction of flow of the exhaust-gas, with such widening existing at least in a first portion of the housing, the flow velocity of the gas in the interior of the housing is diminished. Thereby the dwell time of the exhaust-gas in the chamber will be increased, likewise resulting in a more complete vaporization of the injected fluid. Designing the downstream housing section as a cylindrical tube with an essentially perpendicularly cut end provokes a turbulent flow in the region of the outlet opening, whereby a particularly effective mixing of the enriched gas from the regeneration device with the remaining exhaust-gas stream is ensured.
  • the heating element advantageously includes a porous foam.
  • the latter has a particularly high surface area which is effective for vaporization, allowing a high heat transfer from the heating element to the fluid which is to be vaporized. Also the dwell time of the fluid in the region of the heating element will be correspondingly increased.
  • the foam may be a ceramic foam or a metallic foam.
  • the latter may be wrapped by heating wires or interspersed with these, but it is also possible to apply a voltage directly to the porous material.
  • An additional fluid supply in the vehicle can be dispensed with, if the fluid is a fuel.
  • FIG. 1 shows a schematic partial view of an exhaust-gas system according to the invention.
  • FIG. 2 is an enlarged illustration of a regeneration device, as it is used in the exhaust-gas system of FIG. 1 .
  • FIG. 1 shows a section of an exhaust-gas system 10 which is arranged downstream of a diesel engine of a motor vehicle (not shown).
  • the exhaust-gas system 10 has a first tube section 14 which can be coupled to a manifold through a flange 12 as well as an exhaust-gas cleaning system 16 in the form of a diesel particle filter with an upstream or integrated oxidation-based catalytic converter or in the form of a NO x -storage catalytic converter.
  • the exhaust-gas cleaning system 16 is connected through a second tube section 18 with an end portion (not shown) of the exhaust-gas system 10 .
  • the exhaust-gas system according to the invention may have further exhaust-gas cleaning elements, for instance an oxidation-based catalytic converter which is arranged near the engine, or, in the case of a combination of NO x - and particle reduction, a SCR-catalytic converter.
  • an oxidation-based catalytic converter which is arranged near the engine, or, in the case of a combination of NO x - and particle reduction, a SCR-catalytic converter.
  • a regeneration device 20 is provided which is arranged in the interior of the first tube section 14 immediately upstream of the exhaust-gas cleaning system 16 .
  • the regeneration device 20 comprises an essentially tubular housing 22 which at its upstream side is conically tapered and has a small inflow opening 24 for exhaust gases (see FIG. 2 ).
  • an outlet opening 26 is provided which extends across almost the entire end face of the housing 22 .
  • a chamber 28 is formed in the interior of the housing 22 ; an injection nozzle 30 for fuel extends into this chamber.
  • the injection nozzle is connected with a fuel line of the motor vehicle through a (not shown) fuel pump or metering device.
  • the downstream part of the chamber 28 is almost completely occupied by a heating element 32 which is a porous ceramic foam or metallic foam.
  • this foam is wrapped by a current-carrying wire or interspersed by it, or a voltage is applied to the (electrically conductive) foam itself.
  • a plate-shaped honeycomb-like ceramic structure may be provided as the heating element 32 , which structure has the shape of the internal diameter of the housing 22 .
  • the important point in the selection of the heating element 32 is merely that it has a structure which is distinguished by an as large a surface area as possible and which offers the gas, which flows through it, a certain resistance which is not excessively high.
  • some fuel is injected through the injection nozzle 30 into the chamber 28 towards the heating element 32 .
  • This fuel impinges on the heating element 32 which has a particularly high surface area for vaporizing the fuel, and becomes vaporized.
  • a part of the exhaust gas flows through the inflow opening 24 into the chamber 28 , through the pores or openings of the heating element 32 and finally, entraining the fuel which now is in the vapor state, through the outlet opening 26 out of the housing 22 .
  • a part of the exhaust-gas is used to transport the injected fuel through the heating element 32 .
  • the thermal energy of the exhaust-gas which flows through the chamber 28 is used for additionally heating the heating element, whereby the electric energy which is needed for vaporizing the fuel can be advantageously lowered.
  • electrically produced thermal energy as well as the thermal energy of the exhaust-gas is used for initiating the regeneration of the exhaust-gas cleaning system 16 .
  • the flow velocity of the exhaust-gas reduces in the interior of the chamber 28 .
  • a longer dwell time of the exhaust-gas in the chamber 28 is achieved, whereby a complete vaporizing of the supplied fuel is ensured.
  • the shape of the housing 22 and its arrangement parallel to the outer wall of the first tube section 14 provides for a particularly good mixing of the exhaust-gas, coming from the chamber 28 and enriched with fuel, with the exhaust gas which flows past the housing 22 outside the latter.
  • the difference in pressure between the gas flows due to the differing flow velocities in the interior of the chamber 28 and outside the housing also makes a contribution to this.
