EXHAUST TURBINE APPARATUS |
摘要 |
Apparatus and method for supplying sealing air to an exhaust turbine ( 15 ) that interacts with an internal combustion engine for turbo-compound operation in a vehicle. Exhaust gases from the internal combustion engine are received in an exhaust system having a supercharger turbine ( 11 ) and which drives a compressor ( 13 ) for the engine combustion air. Residual energy in the exhaust gas flow is recovered via the exhaust turbine ( 15 ) for transfer to the crankshaft of the internal combustion engine. The exhaust turbine ( 15 ) is supported in a bearing housing ( 32 ), which is fed with sealing air via a fluid line ( 36 ). The exhaust system includes an exhaust brake throttle ( 16 ) having an exhaust gas pressure regulator ( 22 ) for regulating the exhaust brake pressure. The exhaust gas pressure regulator ( 22 ) is connected via a compressed air line ( 28 ) to a compressed air source ( 29, 30 ), which can be connected in parallel to the bearing housing ( 32 ) via a prioritizing valve ( 35 ) and a compressed air line ( 36 ). |
