ABSTRACT:
An engine system includes an engine, an intake fluid system, and an exhaust fluid system. Furthermore, the engine system includes a turbocharger device including a compressor member in operative communication with the intake fluid stream and an energy supply member in operative communication with the exhaust stream to be actuated thereby. The energy supply member transfers energy to the compressor member, and the compressor member supplies a compressed fluid stream to the engine. Moreover, the engine system includes an aftertreatment device in operative communication with the exhaust stream to treat the exhaust stream. The engine system additionally includes a bypass fluid system that bypasses the internal combustion engine. The bypass fluid system supplies the portion of the compressed fluid stream to the aftertreatment device.
