Exhaust gas flow regulator

Abstract

The invention relates to an exhaust gas flow regulator installed in an exhaust pipeline and to an exhaust pipeline with such an regulator installed therein. The invention also relates to the manufacture and use of the exhaust gas flow regulator and the exhaust pipeline. The exhaust gas flow regulator ( 2, 12, 22 ) according to the invention comprises catalytic corrugated metal plates ( 2 f ) with the corrugation direction of their folds being in an angle towards the average flow direction of the exhaust gas (G) for regulating the exhaust gas flow at least in the lateral direction.
