Definitions
- the invention relates to a claimed with variable GEEinzelnism. Controlled Rußabbrennung and catalyst effect for diesel engines and oil heaters with the Vorteihaft in this new soot particulate filter preamble of claim 1. Use finds. is not just a planned continuous particle cleaning but that the heating element and or or
- the heating elements are play the soot particles with the help of metalliso designed that they partially as a particle filter and or ceramic
- it is advantageous to flow in order to collect the constituent conditions in the arrangement of soot particles in the exhaust gas flow, which are then given with help and flexibility throughout the structure and shape of electrical heating for burning off the sootbake of the soot particle filter , be brought to a wide particle, are also chemical ren advantage of the innovation is also that the means for igniting and burning off the soot particles directly applied particles on the filter element. burned from the inside to the outside, which has the consequence that a substantial part compared to be ⁇
- Particulate filter of the aforementioned type are known from non-contact heating sources substantially to energy of PCT / EP02 / 06724, the burning is saved. It is also advantageous, according to the invention, that these burn-off systems have all the catalytic part in connection with the soot particle disadvantage that the effect of heat on the parking filters in series with Switching, and these are flowed in a particulate so as to house the soot particles which has the advantage of causing the burn-up, these systems require heating volume and the energy to use multiple times, lots of energy, as the exhaust gas flow would be another feature again and becomes an essential part of the hot air foaming, the housing from the inside to the outside with eider soot particles are urgently needed, without Renem thermomante), or from the outside with action in the environment, forcibly a thermo pants to coat This again has unnecessary energy expenditure
- Another advantage is the saving of energy because of the exhaust gas heaters. stored over a longer period of time, and the housing is not deflected by the airstream.
- soot particle filter can be cooled, also the danger is mainly due to the fact that the combination zwiErhitzen the housing to the environment, a fire rule filter unit and the burn-off not held danger.
- the filter medium becomes too high when it is essentially [0009] and the object of the invention is porous and / or unstable in the case of the alist in that the heating units and their ternatives burn off the soot particles with the aid of Arrangement are designed so that they are in itself, as parvon chemical agents that find the exhaust temperature ertikelfilter use.
- the invention has for its object to provide a particulate filter of the type mentioned above to Ab Other objects of the invention and the gas cleaning of internal combustion engines, in particular the scope of the above-described and following for use in motor vehicles to provide the detailed explanations
- Fiä s JL is a view of the filter housing 3an channels and or openings in turns, and with which an input 4 and an output 5 is ring circumferential grooves, depending on the threaded openings for the heating liver May, ceramic filaments screw zusamen- into a bundle mente end face 6 and threaded openings joined on the long side, and then brought by a rotation of the bundle in 7 screwed heating elements with Stomanschluß- a spiral shape, jfkjJ3 23.240 pole 8, a prechamber to the filter unit 9 a Zwidies is possible because the Edelspiralen from materials schenhunt 10 a End chamber 11 is one, the same time serve as a train and compression spring Thermoisoliemg 12 a portion of the catalytic converter, there is a guarantee that the whole gebrown part 13 a section of a filter unit 14 a delte unit unbreakable and shaking elastromschlußpol 15th table are held together.
- R & d heating element 8 with filter discs 18 moderately slender oxidation catalyst and PrismGewindeö réelle on the housing 19 power terminal pole filter attached to each vehicle. 15
- FIG. 5 shows heating element 8 with filter disks 21 introduced into a monolith 22
- an input is located on a filter housing, where the exhaust stream of a diesel engine is introduced into the filter housing 4 this exhaust stream is introduced via the prechamber 9 in the monolith which also serves as a catalyst 13 after leaving the exhaust stream from the catalytic part, it flows again into a hollow chamber 10 from there the exhaust gas stream is introduced into the particle filter 14 and discharged from there into the environment. 11, 5
- stabilization heating elements are screwed to the threaded openings 6, 7 located on the filter housing, 8 ⁇ ML2.
- the stabilization heating elements can be plugged in with the aid of a quick-acting closure Fig. 4.
