A particle trap, which may be installed in a pipe, e.g. in an exhaust tract of a motor vehicle, is provided for the agglomeration and oxidation of particles in a fluid flow and includes a multiplicity of substantially rectilinear and mutually parallel flow passages having passage walls with structures. The structures generate swirling, calming and/or dead zones in the fluid flow but keep the particle trap open to the fluid flow. Therefore, the particle trap is an open system in which particles can be kept or precipitated out of a fluid by turbulences in the flow and can be held until they undergo oxidation. Assemblies and exhaust tracts having the particle trap are also provided. |
