Abstract: An optimized mechanical expander or fluid expansion device with a delayed opening timing is disclosed. In the optimized design, rotors in the expander alternatingly rotate sequentially through an intake position in which the transport volume is open to the housing inlet, a closed position in which the transport volume is closed to the housing outlet, and a discharge position in which the transport volume is open to the housing outlet. During rotation, a first opening forms between the housing and each rotor. After further rotation, a second opening is formed that is located between the first opening and a back end of the rotor. In one aspect, the mechanical expander has an opening profile including an initial opening phase in which the opening between the rotor and outlet forms at a lesser rate than during a subsequent secondary opening phase.

Abstract: A multi-stage expansion device having bypass capabilities and a variable speed drive is disclosed. In one example, the multi-stage expansion device has a housing within which a first stage, a second stage, and a third stage are housed. The housing may also be configured with internal working fluid passageways to direct a working fluid from the first stage to the second stage and/or from the second stage to the third stage. Each of the stages may include a pair of non-contacting rotors that are mechanically connected to each other and to a power output device such that energy extracted from the working fluid is converted to mechanical work at the output device. In one example, a bypass line is provided to bypass working fluid around the first stage and a bypass line is provided to bypass working fluid around the second stage.

Abstract: An exhaust gas energy recovery system includes an internal combustion engine, a volumetric fluid expander, and a water injection mechanism. The internal combustion engine includes an air inlet, at least one cylinder, and an exhaust gas outlet for conveying an exhaust gas stream at a first pressure. The volumetric fluid expander generates useful work at an output shaft by expanding the exhaust gas stream to a second pressure lower than the first pressure as the exhaust gas stream moves through the volumetric fluid expander. The water injection mechanism injects water into the system at a location between the air inlet of the engine and the expander to increase the volume of the exhaust received by the expander for increased power output at the expander.

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.
