Abstract

Abstract The intention is to lower the flow resistance of a filter device in the exhaust flow of an internal combustion engine, in particular a diesel engine. For this purpose, the free cross-section of the outlet opening (12) at which the exhaust flow emerges into the environment is at least substantially equal to the flow cross-section in the filter device (1). <IMAGE>
