Abgassystem für eine Verbrennungskraftmaschine

摘要

The invention concerns an exhaust-gas system for an internal-combustion engine, in particular a vehicle internal-combustion engine, preferably a four-stroke vehicle internal-combustion engine. Located in the exhaust-gas system is a catalytic device (4) with at least one electrically heated honeycomb element (5) through which the exhaust gases flow, the honeycomb element being mounted in a housing (12) and connected by leads (9, 10) to terminals on the housing (12). The device (4) is electrically isolated from the exhaust-gas system. To isolate the device (4) from the exhaust-gas system, the housing has electrical insulation (15) at the gas-entry and gas-outlet ends (6, 7).
