Double-flow exhaust system for combustion engine in motor car, has delay device designed to produce running time difference of exhaust gas when exhaust gas of engine flows between exhaust lines through system

摘要

The system (1) has first and second exhaust lines (3, 4) fluidically and operatively connected with each other by a connection section (17). The second exhaust line differs from the first exhaust line and comprises an equaled tube length as the first exhaust line. One of the exhaust lines has a delay device (20) i.e. interference damper, arranged downstream to the connection section and designed to produce a running time difference of exhaust gas when exhaust gas of a combustion engine (2) flows between the exhaust lines through the system.
