摘要： A filter device with a preferably hollow-cylindrical, pleated filter element which is arranged concentrically around a cylinder axis and through which a medium to be filtered passes. Seals are necessary on the filter device so that the medium to be filtered will not be able to leak out and so that the filter element, which typically is constructed of filter paper, must be fixed in place together with its pleats. Advantageously, an elastic composition can be disposed as a seal on at least one of the ends of the filter element, and after curing the elastic composition will fix the pleats of the filter element and will have sufficient residual elasticity to seal the filter element with respect to a central mounting tube on which it is to be mounted.

摘要： The invention relates to a process for the discontinuous burning off of carbon deposited on the heat-resistant exhaust gas filter of an internal combustion engine, particularly a diesel internal combustion engine. At least one metal must be present during this process. The problem of ensuring the combustion of the carbon at the minimum temperature and of achieving a long filter life, is solved in a particularly advantageous manner through the use of an organic complexing agent able to form a complex with the metal and/or an organo-metallic complex compound of the metal with the organic complexing agent.The invention also relates to an apparatus for performing the inventive process. For this purpose, the exhaust gas filter preferably has at least two, at least temporarily separately operable filter units.

摘要： The invention relates to a means and a method for removing soot in an exhaust gas filter of an internal combustion engine, more especially a diesel engine, by reducing the ignition temperature during the operation of the internal combustion engine. For this purpose, the ignition is brought about by the addition of at least one oxidizing agent. A plurality of particles of at least one combustible substance may also be caused to flow or burn, and the particles may be passed through the exhaust gas stream to the filter, so that the soot layer is ignited.

摘要： An air filter element, in particular for the cleaning of combustion air for internal combustion engines, in air filters with a substantially cylindrical, air-permeable housing. The air filter element has a raw air inlet area (2) and a clean air outlet area (3). The clean air outlet area is arranged substantially concentrically on one of the end surfaces of the cylindrical housing (1), and the raw air inlet area occurs substantially across the surface of the housing (1). An air-permeable center tube (4) connecting to the clean air outlet area extends inside the housing (1), and a substantially metal-free filter insert (5) is slid over the center tube (4) and separates the clean air from the raw air side. The opposite end surface (7) of the insert is sealed, and the clean air outlet side of the housing (1) has an axial seal (8) on the face thereof, it being possible to divide the housing (1).

摘要： A soot filter has sets of three to five filter tubes disposed in a circle and axially parallel to one another, through which exhaust flows radially from the outside in during operation, composed of refractory ceramic yarn wound spool-wise to form hollow cylinders. To permit an electrical burn-off of the deposited soot with a relatively low expenditure of energy, the clearance A of all adjacent filter tubes 30 from one another amounts to 2 to 4% of the average filter tube diameter D. In each interstice 36 formed by at least three filter tubes 30 an elongated electrical heating element 37 is disposed which can be turned on if the exhaust gas stream is interrupted by shutting down the internal combustion engine or by diverting the exhaust gas stream away from a set of filter tubes.
