Abstract
A simple exhaust system is disclosed with improved operational reliability and an increased service life for a turbocharged internal combustion engine, in which system both the advantages of shock-wave charging and those of pulse-converter charging are used, depending on the operating state of the internal combustion engine. These advantages are achieved by virtue of the fact that extension pieces (12, 13) are formed for the shock pipes (6, 7) and are arranged upstream of the connection line (8, 9) furthest away from the exhaust turbine (5). Each shock pipe (6, 7) is connected to a corresponding extension piece (12, 13). The interconnection conduit/s (14) is/are formed between the extension pieces (12, 13). Each interconnection conduit (14) has a cross-sectional constriction (15).
