Abstract
Exhaust gas from a first outlet port () of a cylinder () of a combustion engine () can flow through the first turbocharger (), and exhaust gas from a second outlet port () of the cylinder () can flow through the second turbocharger (). A first connecting duct () can supply the second turbine () with exhaust gas from the first turbine (). The first connecting duct () is connected to a first bypass duct () that issues into a tailpipe line () downstream of the second turbine () to bypass the second turbine (). The first bypass duct () has a second control valve () that can block the first bypass duct (). The first connecting duct () has a first control valve () that can block the first connecting duct () to prevent exhaust gas from flowing through the first turbine () to the second turbine ().
