摘要:
Cross-sectional geometries of filter elements for soot particle filters are described, allowing uniform loading of the filter element with soot. Starting with hexagonal cell shapes, other polygonal shapes are arranged around them. All the cross-sectional geometries have in common the fact that the cross-sectional area of all inlet channels is larger than the cross-sectional area of all outlet channels.

摘要:
A filter element for an exhaust-gas aftertreatment device of an internal combustion engine is provided, which is made of a coated ceramic material and thus is more robust with respect to local overheating.
摘要:
A filter device and a method for cleaning gas mixtures containing particles, e.g., soot-containing exhaust gases of internal combustion engines, as well as a method for the manufacture of the filter device, are provided. The filter device has a porous surface made of a filter base material exposed to the gas mixture to be cleaned. A layer of ceramic fibers is applied onto the surface exposed to the gas mixture to be cleaned.
摘要:
A filter device, in particular for an exhaust-gas system of an internal combustion engine, includes a filter structure having at least one filter wall. Filtered-out particles are deposited on its upstream surface. It is provided that the upstream-lying surface of the filter wall is at least regionally uneven.
摘要:
An exhaust treatment device and a carrying structure for treating the exhaust of an internal combustion engine, in particular an autoignition internal combustion engine of a motor vehicle, as well as a method for manufacturing a corresponding device, having a support structure, in which the exhaust is able to interact with the support structure in order to treat the exhaust and in which a fiber layer is situated on the surface of the support structure. The fiber layer improves the contact of the exhaust with the surface of the exhaust treatment device.
摘要:
A filter element, in particular for filtering exhaust gases of an internal combustion engine, includes mutually parallel flow channels, at least two filter segments being provided which each have a subset of flow channels, the filter segments having a spacing from one another and being interconnected via connecting device(s) arranged integrally with the filter segments.
摘要:
A filter element and a soot filter in which the temperature distribution over the cross-section of the filter element can be kept constant in first approximation.
