Automotive diesel engine exhaust filter has series of linked discrete particle filters in decreasing particle trap size

An automotive diesel engine exhaust system has a particle filter (14) assembly with a filter insert (20) in a common housing (16). The exhaust filter assembly comprises two or more discrete filters arranged (20a-c) in series but separate from each other. The two filters have different properties and...

Beschreibung
Zusammenfassung:	An automotive diesel engine exhaust system has a particle filter (14) assembly with a filter insert (20) in a common housing (16). The exhaust filter assembly comprises two or more discrete filters arranged (20a-c) in series but separate from each other. The two filters have different properties and different dimensions and are linked by an exhaust pipe. The first filter traps coarse particles and the second filter traps finer particles. Each filter incorporates a condition sensor. Eine Filtervorrichtung (14), insbesondere ein Dieselpartikelfilter, für eine Abgasanlage (12) einer Brennkraftmaschine (10) umfasst mindestens ein Gehäuse (16) und mindestens einen Filterkörper (20). Es wird vorgeschlagen, dass die Filtervorrichtung (14) mindestens zwei fluidisch in Serie angeordnete Filterkörper (20a, 20b, 20c) umfasst.
