Engine and induction generator

摘要

An internal combustion power-plant comprising a combustion housing having a crankshaft that is driven when a fuel is combusted in the combustion housing. An induction generator is positioned around the combustion housing. The induction generator includes a stator connected to an outer surface of the combustion housing and an induction rotor that rotates about the stator. The induction rotor and the crankshaft are mechanically coupled to a sprocket via a clutch mechanism. The stator is electrically connected to power electronics that are within a nacelle that supports and surrounds the power-plant, as well as acts as a heat exchanger for the power-plant and power electronics closed loop cooling system. The induction generator operates as a generator to draw power off the crankshaft, via the clutch mechanism, to rotate the induction rotor which in turn induces current in the stator.

1. An internal combustion power-plant, comprising:
a combustion rotor housing having a combustion chamber bore and a common axis of rotation, a combustion rotor having a combustion rotor axis, and a crankshaft having a lobe, an aperture, and a crankshaft axis, the lobe having a lobe axis spaced from the crankshaft axis, wherein the common axis and the crankshaft axis are co-axial, and the combustion rotor axis and the lobe axis are co-axial; a compressor-turbine shaft having a first end and a second end, the compressor-turbine shaft being co-axial with the common axis and located within the aperture of the crankshaft, the crankshaft and compressor-turbine shaft are unconnected and rotate independently; a compressor wheel located at the first end of the compressor-turbine shaft at an air intake end of the power-plant, the compressor wheel having a plurality of compressor fins; a turbine wheel located at the second end of the compressor-turbine shaft at an air exhaust end of the power-plant, the turbine wheel having a plurality of turbine fins; and an induction generator positioned around the combustion rotor housing, the induction generator including a stator and an induction rotor, the induction rotor rotating about the stator, the induction rotor being mechanically coupled to the crankshaft, and the stator being electrically connected to a power electronics: and a nacelle that surrounds and supports the combustion rotor housing and the induction generator, the nacelle having a plurality of cooling fins disposed about an interior surface thereof, the nacelle further having at least one fluid-filled cooling port and a liquid-to-liquid heat exchanger that extends through the at least one fluid-filled cooling port and transports a first liquid heated by the combustion rotor housing to the at least one fluid-filled cooling port, whereby heat from the first liquid is transferred to a second fluid of the at least one fluid-filled cooling port, and then from the second fluid of the at least one fluid-filled cooling port to the fins, the fins being cooled by air circulating through the nacelle.
