Supercharged internal combustion engine for vehicle propulsion has cold air turbine operation as second operating state

摘要

The engine (25) has an exhaust gas turbo-supercharger with a compressor (100) in the engine induction system supplied with induction air for compression in the first operating state. The second operating state is cold air turbine operation, in which the aid sucked in goes to the compressor. The induction system includes two pipelines. The first one is controlled by an adjustable guide valve (E) and the second one by another such valve (F). The compressor has its own valve (C).
