VERBRENNUNGSMOTOR MIT ZWEISTUFIGEM TURBOLADESYSTEM

摘要

The invention relates to an internal combustion engine (10) with an exhaust gas pipe (15, 16) for taking exhaust gases from the engine's combustion chamber (11) and an intake pipe (12) for supplying air to the said combustion chamber. The engine comprises a turbo charging system with a high-pressure turbine (17) that interacts with a high-pressure compressor (19) and a low-pressure turbine (21) that interacts with a low-pressure compressor (23), for recovery of energy from the engine's exhaust gas flow and pressurizing of the engine's intake air. The high-pressure turbine (17) is connected to the low-pressure turbine (21) via a duct (20). An exhaust gas pressure regulator (20a) is located in the duct (20) between the high-pressure turbine (17) and the low-pressure turbine (21).
