METHOD AND DEVICE FOR OPERATING A SYSTEM TO CONVERT AT LEAST ONE EXHAUST-GAS COMPONENT OF AN EXHAUST-GAS STREAM OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a system for converting at least one exhaust-gas component of an exhaust-gas stream of an internal combustion engine (1), comprising a first device (2) having a catalytic action and a second device (3) which is positioned downstream of the first device (2) in the direction of flow of the exhaust-gas stream. The second device (3) has at least one electrically heatable first honeycomb body (4), a second honeycomb body (5) presenting at least one coating which at least partly absorbs at least hydrocarbons, and a third electrically heatable honeycomb body (6), which bodies are arranged behind each other in the direction of flow of the exhaust-gas stream.
