Abstract

Die vorliegende Erfindung betrifft einen statischen Mischer (12) für eine Abgasanlage (7) zum Vermischen eines Reduktionsmittels mit einer Abgasströmung (8), mit mehreren Leitschaufeln (14) zur Umlenkung der Abgasströmung (8).
Ein reduzierter Strömungswiderstand ergibt sich, wenn wenigstens eine der Leitschaufeln (14) eine von der Abgasströmung (8) durchströmbare Perforation (25) aufweist.
