Abstract
Methods and systems are provided for reducing exhaust energy delivered to a turbine of a turbine-generator coupled to a split exhaust engine system in order to reduce turbine over-speed conditions and/or to reduce a generator output. In one example, a method may include retarding a first timing of a first exhaust valve utilized to deliver a blowdown portion of exhaust energy to the turbine, and/or advancing a second timing of a second exhaust valve utilized to deliver a scavenging portion of exhaust energy to an exhaust catalyst in response to a turbine speed greater than a threshold speed.
