Abstract
An internal combustion engine is provided with an exhaust gas pipe for taking exhaust gases from the engine's combustion chamber and an intake pipe for supplying air to the combustion chamber. The engine includes a turbo charging system with a high-pressure turbine that interacts with a high-pressure compressor and a low-pressure turbine that interacts with a low-pressure compressor, for recovery of energy from the engine's exhaust gas flow and pressurizing of the engine's intake air. The high-pressure turbine is connected to the low-pressure turbine via a duct. An exhaust gas pressure regulator is located in the duct between the high-pressure turbine and the low-pressure turbine.
