Abstract: An engine system including a power plant, an intake assist device connected to an air inlet of the power plant, and an expander connected to an exhaust outlet of the power plant is presented. A motor/generator is connected to power the expander to selectively provide power to and capture power from the expander. An expander controller is connected to control the motor/generator connection to the expander, and is configured to select between a passive mode, where exhaust passively moves through the expander, and an active mode, where the motor/generator powers the expander to actively draw exhaust from the exhaust manifold. In one example, the air intake and exhaust flows are controlled independently of the rotational speed of the power plant.

Abstract: In one aspect, the teachings presented herein include a power generation system including: a power plant having an air intake and an exhaust outlet; a boost device in fluid communication with the power plant air intake, the boost device being for pressurizing air entering the power plant air intake; a waste heat recovery device in fluid communication with the power plant exhaust outlet, the waste heat recovery device being for recovering energy from exhaust from the power plant; a first motor/generator coupled to the boost device; a second motor/generator coupled to the waste heat recovery device; an energy storage device for storing energy generated by the first and second motor/generators and for delivering power to drive the first motor/generator; a controller for controlling the first and second motor/generators, wherein the controller is configured to control the level of power generated by the waste heat recovery device based on a state of charge of the energy storage device.
