Exhaust gas purification device for IC engine having turbocharger has devices for oxidizing exhaust gases exiting engine and fed to turbine of turbocharger

摘要

An exhaust gas purification device has devices for oxidizing exhaust gases exiting the engine and fed to a turbine of the turbocharger. Preferred Features: The oxidation devices contain a catalyst (17). The catalyst is arranged in an exhaust gas collecting pipe (8) of the engine. The collecting pipe has a catalytically active layer (18) on its inner side. Fibers with a catalytically active surface are arranged in the collecting pipe. A perforated sheet bent into a tube with a catalytically active surface is arranged in the collecting pipe.
