Abstract

See full text

Exhaust gas from a first outlet port (5) of a cylinder (3) of a combustion engine (2) can flow through the first turbocharger (7), and exhaust gas from a second outlet port (6) of the cylinder (3) can flow through the second turbocharger (17). A first connecting duct (28) can supply the second turbine (19) with exhaust gas from the first turbine (9). The first connecting duct (28) is connected to a first bypass duct (29) that issues into a tailpipe line (32) downstream of the second turbine (19) to bypass the second turbine (19). The first bypass duct (29) has a second control valve (44) that can block the first bypass duct (29). The first connecting duct (28) has a first control valve (43) that can block the first connecting duct (28) to prevent exhaust gas from flowing through the first turbine (9) to the second turbine (19).
