Abstract
A method for purifying the exhaust gas generated by an internal combustion engine, wherein the exhaust gas generated by the internal combustion engine is conducted through an exhaust gas path in which at least one adsorption element is arranged, to which pollutants contained in the exhaust gas at least partly bind, and in which the at least one adsorption element is regenerated by at least partial desorption of the bound pollutants, and pollutants desorbed from the at least one adsorption element during the desorption process are stored in at least one storage unit.

A method for purifying exhaust gas generated by an internal combustion engine, comprising:
- generating the exhaust gas by the internal combustion engine through an exhaust gas path in which at least one adsorption element is arranged, to which pollutants contained in the exhaust gas at least partly bind,
- and in which the at least one adsorption element is regenerated by at least partial desorption of the bound pollutants,
- and pollutants desorbed from the at least one adsorption element during the desorption process are stored in at least one storage unit.
An exhaust gas system for an internal combustion engine, comprising:
- an exhaust gas path and at least one adsorption element arranged in the exhaust gas path, wherein the at least one adsorption element is configured to at least partly bind pollutants contained in the exhaust gas in an adsorption process,
- wherein the at least one adsorption element is configured to be regenerated by at least partial desorption of the bound pollutants, and
- wherein the exhaust gas system comprises at least one storage unit, which is designed to store pollutants desorbed from the at least one adsorption element during a desorption process.
