Exhaust system and method for reducing exhaust gas temperature
The exhaust system for an internal combustion engine (1) comprises a high-pressure turbocharger (3), means (2, 7) for establishing flow communication between the engine (1) and the turbocharger (3), a low-pressure turbocharger (4), means (6) for establishing flow communication between the turbines (...

| description | The exhaust system for an internal combustion engine (1) comprises a high-pressure turbocharger (3), means (2, 7) for establishing flow communication between the engine (1) and the turbocharger (3), a low-pressure turbocharger (4), means (6) for establishing flow communication between the turbines (3a, 4a) of the turbochargers (3, 4), and a heat exchanger (5) that is arranged upstream from the turbine (3a) of the high-pressure turbocharger (3) and comprises a cooling medium duct (17). The system further comprises means (6, 11) for guiding exhaust gases from the downstream side of the high-pressure turbocharger (3) into the cooling medium duct (17) of the heat exchanger (5) for reducing the temperature of the high -pressure exhaust gases in the heat exchanger (5). The invention also concerns a method for reducing exhaust temperature. |
