Definitions

  • the present invention relates to a combustion chamber assembly for a vehicle heater, which is used for example as a parking heater or as a heater in a vehicle.
  • Such combustion chambers are generally designed in such a way that an ignition organ receiving projection, also referred to as a plug neck, is provided on an approximately pot-like combustion chamber housing with a circumferential wall and a bottom region on the circumferential wall, which limits an open volume region to a combustion chamber formed in the combustion chamber housing.
  • an ignition organ receiving projection also referred to as a plug neck
  • a porous evaporator medium is provided, and the fuel supply via a fuel line, which opens into the Zündorganingansatz and thus introduces the liquid fuel into the provided therein porous evaporator medium.
  • the fuel is distributed not only in the provided in the Zündorganingansatz porous evaporator medium, but passes from this in the porous evaporator medium on the inside of the peripheral wall.
  • the feeding of the liquid fuel in the area of the Zündorganingansatzes ensures that in the starting phase, in which are provided in this locally very limited range by exciting the ignition sufficiently high temperatures, a sufficient amount of fuel is available to start the combustion. Only in the started combustion operation, the flame then spreads further into the combustion chamber, so that the required combustible mixture is provided by the there and via the evaporator medium on the inside of the peripheral wall evaporating liquid fuel and the combustion air also fed into the combustion chamber and burned becomes.
  • a problem of such combustion chamber assemblies is that the distribution characteristic is very strongly dependent on the installation position of the combustion chamber assembly or of a vehicle heater having it due to the locally very limited fuel feed. It must always be ensured that a positioning is found in which the Zündorganoritsatz is in an upper range, so that the action of gravity supports the fuel distribution and does not counteract it. Also, in such an embodiment, it is difficult to ensure in all operating states of a vehicle heater that the temperature in the region of the fuel inlet is not so high that the fuel initially fed in liquid starts to boil, since this leads to considerable deposits in the area of the fuel inlet , Here is especially the shutdown of such a heater in which the combustion is to be stopped, critical.
  • a combustion chamber assembly for a vehicle heater comprising a combustion chamber housing having a peripheral wall and a bottom region surrounding a combustion chamber, at least two Zündorganfactanharme open to the combustion chamber on the peripheral wall, on an inner side of the peripheral wall and at least one of the combustion chamber approaches a porous An evaporator medium, a Brennstoffzumoltechnische extractor for supplying fuel to the porous evaporator medium in the at least one of the fuel receiving lugs, on the inside of a porous evaporator medium is provided, and in at least one of the Zündorganfactan accounts an electrically excitable ignition device.
  • a porous evaporator medium be provided on the inside of each of the Zündorganama.
  • the provision of ignition devices in all Zündorganingst algorithmsn allows, for example, at relatively low ambient temperatures a much shorter start-up phase, since the combustion starting from several local areas, namely the respective Zündorganingst algorithmsn is started. This is particularly advantageous when such a vehicle heater is to be operated as a heater, i. when an internal combustion engine of a vehicle is started, as soon as possible to provide additional heat energy.
  • two Zündorganinganticiane are provided and the two Zündorganinganticiane with respect to a longitudinal center plane or a longitudinal center axis of the combustion chamber to each other are arranged substantially symmetrically. Due to the symmetry with respect to a longitudinal center plane, ie essentially a mirror symmetry, or also the symmetry with respect to a longitudinal center axis, ie essentially a point symmetry, the uniformity of the fuel introduction and also of the heat energy introduction in the starting phase is further improved.
  • FIG. 1 shows a combustion chamber assembly 10 as used in a vehicle heater used as a heater or auxiliary heater.
  • the combustion chamber assembly 10 comprises a substantially cup-shaped combustion chamber housing 12 with an approximately cylindrical peripheral wall 14 and at an axial end portion, axially relative to a longitudinal center axis A of the combustion chamber housing 12, a bottom portion 16.
  • the combustion chamber housing 12th open to the exit of the combustion products.
  • the floor area 16 has an approximately axially extending combustion air inlet nozzle 18 with a plurality of, for example, slot-like openings 20 for the entry of combustion air into a combustion chamber 24 provided in the combustion chamber housing 12.
  • two approximately cylindrical Zündorganinganharmae 26 are provided on the peripheral wall 14 of the generally made of metal material combustor housing 12. These are open to the combustion chamber 24 and open approximately tangentially in this one. It can be seen in FIG. 2 that the two Zündorganinganticiane 26 may for example be arranged at an acute angle to each other and are preferably positioned on the peripheral wall 14 so as to give a symmetrical arrangement. In the embodiment variant shown in FIG. 2, the two Zündorganingan instruments 26 with respect to a already mentioned longitudinal center axis A and, for example, in the illustration of FIG. 1 orthogonal to the plane of longitudinal longitudinal plane E are arranged in mirror image symmetrical.
  • the two Zündorganingan accounts 26 are preferably also made of metal and may be connected to the peripheral wall 14 by welding or soldering, but can also be produced with this integrally, for example in a casting process.
  • a porous evaporator medium 28 which is adapted to the shaping of the circumferential wall and likewise provided in a substantially cylindrical configuration, is provided.
  • This preferably coats the entire combustion chamber 24 and provides the surface over which liquid fuel in vapor form can be delivered into the combustion chamber 24.
  • the two Zündorganingan accounts 26 are each lined on its inside with porous evaporator medium 30. Again, an arrangement is provided in which the Zündorganingan accounts 26 preferably on the entire Are lined inside and further in which the respective porous evaporator medium 30 extends into the region of the porous evaporator medium 28 on the inside of the peripheral wall 14 and is in communication therewith.
  • the porous evaporator medium 28 on the inside of the peripheral wall 14 and the respective porous evaporator medium 30 on the inside of the respective Zündorganfactansatzes 26 may be constructed of nonwoven material, braid, knitted fabric, ceramic foam or other material in its interior volume pore having material, wherein the porosity on the viscosity of to be used liquid fuel is tuned so that a distribution of the in the inner volume region of a respective porous evaporator medium 28 and 30 reached liquid fuel also takes place under capillary force.
  • the feed of the liquid fuel takes place in the region of the two Zündorganingan accounts 26 by a respectively opening into this fuel line 32.
  • the supplied via the respective fuel line 32 fuel thus enters the porous evaporator medium 30 of each Zündorganingansatzes 26 and initially distributed primarily in this porous evaporator medium 30th
  • this porous evaporator medium 30 due to the contact of this porous evaporator medium 30 with the porous evaporator medium 28, the already mentioned feed of the fuel in liquid form into the region of the combustion chamber 24 takes place.
  • the fuel is then discharged in vapor form into the inner volume region of the respective Zündorganingansatzes 26 and the combustion chamber housing 12 at the inwardly exposed surface of the porous evaporator medium 30 and 28 to there together with the supplied via the supply port 18 combustion air an ignitable mixture form.
  • one or more openings are present in the region of the ignition element receiving lugs 26, via which air can be introduced in order to further support the formation of an ignitable mixture in these ignition element receiving lugs 26.
  • each of the Zündorganingan accounts 26 an example designed as Glühzünd21 or glow plug igniter 34 is provided. This can be carried on a respective Zündorganingansatz 26 on its side facing away from the combustion chamber side carrier element 36. Through this support element, a connecting element 38 can continue to be guided, which allows the electrical contacting of the respective ignition member 34.
  • a combustion chamber assembly 10 As shown in Figs. 1 and 2 and described above, various advantages can be obtained in operation.
  • both Zündorganinganticiane 26 with an ignition device 34.
  • These can be operated simultaneously in the starting phase, so that, of course, simultaneous fuel feed via the associated lines 32, the combustion is started starting from two local areas and thus the start phase can be made significantly shorter. Since in such a start phase two ignition elements 34 are to be excited simultaneously, there is a higher load of the on-board voltage system, since the double current flow is to be expected, as with excitation of only one ignition device. Due to the time-phase but significantly shortened start-up phase, the energizing of two ignition devices 34 means no or no substantial increase in the required energy. Of course, it is possible to specify in such a start phase, provided at the then at least in phases at the same time to be excited ignition devices 34 electrical heating corresponding to the desired starting procedure.
  • a further advantage of the arrangement according to the invention is that a plurality of distributed regions for fuel injection are created by a plurality of Zündorganfactanticiane 26, each with associated porous evaporator medium 30 and fuel line 32, but are located away from the areas with relatively high combustion temperatures.
  • the amount of fuel to be distributed to the various Zündorganaufnahmake accounts 26 can be distributed according to the requirements occurring. For example, may be provided by a conventional branch in a main supply that each of the areas to be supplied with the same amount of fuel is supplied, or that locally different amounts of fuel are fed, for example by providing corresponding throttle points.
  • the distributed fuel feed also has the advantage of a more uniform temperature level in the combustor 24, which also counteracts the tendency of scale generation and generally counteracts the formation of pollutants.
  • the cooling of the combustion chamber can be prevented especially during cold starts, so when starting in the temperature range of -30 ° C to -40 ° C, and thus the risk of flame breaks are reduced. It is also important that in the presence of multiple ignition organs failure of an ignition device is acceptable, since in principle the heater can then be started with the existing ignition or the organs. So it is then not necessary, for example, visit a workshop immediately because of the failure of an ignition device. In principle, it is then possible to continue working with the remaining ignition device, at least until routine maintenance is required.
