System for post-treatment of exhaust gases of boost pressure operated combustion engine, has burner, which conducts hot exhaust gases into exhaust line of internal-combustion engine through conduit upstream nitrogen oxide-storage catalyst

摘要

System, has a burner (22), which conducts hot exhaust gases into exhaust line (12) of internal-combustion engine (10) through conduit (24) upstream nitrogen oxide-storage catalyst (18). A partial air flow line (28) diverts from the load air line (21) upstream of the combustion engine and supplies a partial amount of the load air flow to the burner during a regeneration phase of the nitrogen oxide-storage catalyst. An independent claim is also included for post-treatment of exhaust gases of boost pressure operated combustion engine.
