Abstract: A combined exhaust gas noise silencer consisting of a system of hollow elements with a mutual housing comprising a front face of the silencer connected to the supply pipe of exhaust gases, and a rear face of the silencer with an outlet from the rear face of the silencer, where the original—inlet exhaust gas (?p) carrying a noise wave is divided into at least two flows—an exhaust gas flow (?z) carrying a shifted noise wave with delayed wave length, and an exhaust gas flow (?n) carrying a non-shifted noise wave, which are subsequently combined into a common exhaust gas flow (?s).
