The invention relates to a method for purifying exhaust gas generated by an internal combustion engine. The exhaust gas generated by the internal combustion engine is conducted through an exhaust gaspath that is equipped with at least one adsorption element (12a, 12b) to which pollutants contained in the exhaust gas at least partly bind. The at least one adsorption element (12a, 12b) is regenerated by at least partly desorbing the bound pollutants, and pollutants desorbed from the at least one adsorption element (12a, 12b) during the desorption process are stored in at least one storage unit. 本发明涉及一种用于净化由内燃机产生的排气的方法，其中，将由内燃机产生的排气引导通过排气路径，在该排气路径中布置至少一个吸附元件(12a、12b)，使包含在排气中的有害物质至少部分地结合在该吸附元件上，其中，所述至少一个吸附元件(12a、12b)通过至少部分地解吸被结合的有害物质而再生，其中，将在解吸期间从至少一个吸附元件(12a、12b)中解吸出的有害物质存储在至少一个存储器中。
