摘要： A process is described for producing filter elements which contain a cross-wound yarn as the filter material, wherein twisted yarn of fine individual fibers is roughened to enhance its filtering action. The yarn may be heat-resistant and the filter element may be used as a soot filter in the exhaust gas stream of an internal combustion engine. Before the yarn is wound up, fiber tufts are broken up by pulling the yarn under tension over a moving roughening surface, the direction of movement of the roughening surface differing by an angle alpha from the direction of movement of the yarn in the area of contact between the yarn and the roughening surface, and the angle alpha being selected in relation to the twist of the yarn, particularly so that the threads of the yarn in contact with the roughening surface are oriented transversely to the direction of movement of the roughening surface. The process produces a roughened yarn which provides the required high filter performance for a soot filter.

摘要： A soot collector, e.g., for collection of soot from the exhaust gases of a diesel-powered internal combustion engine, having a fluid metering device which makes possible exact metering of a specified quantity of a soot remover by a controlled flow of compressed air onto the filter medium of the soot collector for regeneration of the filter medium, and which works reliably and can be manufactured economically. The fluid metering device of the soot collector includes a reservoir, a metering tank arranged in the vicinity of the reservoir bottom, a line which bypasses the metering tank, and a fluid inlet opening in the metering tank which can be closed in response to a flow of compressed air through the metering tank.

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.
