Systems and methods for controlling a turbogenerator by valve deactivation in a shared exhaust engine system

摘要

There are provided methods and systems for reducing exhaust energy supplied to a turbine of a turbogenerator coupled to a split exhaust engine system to reduce turbine overspeed conditions and / or to reduce generator output. In one example, a method may include deactivating an exhaust bleed valve that is used to supply a pre-blown portion of exhaust energy to the turbine.
