FORCED INDUCTION DEVICE FOR A COMBUSTION ENGINE, COMBUSTION ENGINE AND METHOD FOR OPERATING A COMBUSTION ENGINE

摘要

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).

1. A forced induction device for a combustion engine, comprising: first and second exhaust turbochargers, exhaust gas emerging from a first outlet port of a cylinder of the combustion engine flowing through the first exhaust turbocharger, and exhaust gas emerging from a second outlet port of the cylinder flowing through the second exhaust turbocharger, a first connecting duct downstream of a first turbine of the first turbocharger and upstream of a second turbine of the second exhaust turbocharger for supplying the second turbine with exhaust gas from the first turbine, the first connecting duct being connected to a first bypass duct at a first branch, the first bypass duct issuing at a first entry into a tailpipe line downstream of the second turbine to bypass the second turbine, the first bypass duct having a second control valve for blocking or opening the first bypass duct, and the first connecting duct having a first control valve that can block or open the first connecting duct to prevent exhaust gas from flowing through the first turbine to the second turbine.
