Multi-cylinder internal combustion engine for low exhaust gas (EG) temperatures, has a cylinder head with outlets into an EG manifold and an EG collector chamber with catalytically active material

摘要

A cylinder head (1) has outlet channels running into an exhaust gas manifold (EGM) (2) with exhaust gas inlet holes (EGIH) (3) assigned to every outlet channel and running into an exhaust gas collector chamber (ECC) (4) in the EGM. The ECC contains a catalytically active material (6) and has an area (5) that is assigned to the EGIH and free from catalytically active material.
