An exhaust system, comprising:
- an exhaust gas recirculation line configured to recirculate an exhaust gas of an internal combustion engine;
- a device disposed in said recirculation line and configured to separate particles from the exhaust gas;
- said device including a pot having a base with a multiplicity of openings formed therein, a cover, and at least one nonwoven layer disposed at said base and positioned between said base and said cover.
A motor vehicle, comprising:
- an exhaust-gas recirculation system equipped with a device for separating particles from an exhaust gas of an internal combustion engine;
- said device including a pot having a base with a multiplicity of openings formed therein, a cover, and at least one nonwoven layer disposed at said base and positioned between said base and said cover.
A method for operating an exhaust system, the method comprising the following steps:
- providing an exhaust gas recirculation line;
- providing a device in the recirculation line, the device including a pot having a base with a multiplicity of openings formed therein, a cover, and at least one nonwoven layer disposed at the base and positioned between the base and the cover;
- recirculating an exhaust gas of an internal combustion engine through the exhaust gas recirculation line;
- and
- separating particles from the exhaust gas in the device.
