A compound cycle engine system has a rotary engine, which rotary engine generates exhaust gas. The system further has a compressor for increasing the pressure of inlet air to be supplied to the engine to a pressure in the range of from 3.0 to 5.0 atmospheres and an intercooler for providing the inlet air to the engine at a temperature in the range of from 150 to 250 degrees Fahrenheit. The system further has one or more turbines for extracting energy from the exhaust gas. The Miller Cycle is implemented in the rotary engine, enabling the compression ratio to be lower than the expansion ratio, allowing the overall cycle to be optimized for lowest weight and specific fuel consumption.

Methods, apparatuses, media and signals for supplying energy to an energy bus in communication with an energy generating device and with a regenerative braking system in a hybrid electric vehicle are disclosed. One such method includes controlling power supplied by the energy generating device to the energy bus, in response to a braking signal indicative of user brake actuation. Another such method involves controlling energy contributions onto the energy bus from the energy generating device and from the regenerative braking system respectively, to prevent the contributions from exceeding a desired total energy contribution. The energy generating device may include an auxiliary power unit, such as fuel cell, or a generator coupled to a prime mover such as an internal combustion engine, for example.

A hybrid electric vehicle includes an internal combustion engine, an electric motor and a transmission. A turbocharger is in fluid communication with the internal combustion engine. Moreover, a generator is mechanically coupled to the turbocharger and thereby driven by exhaust gas from the internal combustion engine. The generator can provide electricity to the motor and / or a battery while simultaneously providing altitude compensation for the internal combustion engine so that the internal combustion engine output remains at the same power and efficiency as altitude and environmental conditions change. The turbocharger can also be used for power boost if desired. The exhaust gas driven generator system can be deployed in conventional vehicles as well to charge the battery and / or power electrical accessories, thereby replacing the alternator.

An electrically variable transmission includes a power source, three differential gear sets, first and second motor / generators each connected to at least one of the gear sets, and torque-transmitting mechanisms. An input member transfers power from the power source through the differential gear sets to an output member. The torque-transmitting mechanisms are selectively engageable to provide an input-split first electrically variable mode having equal forward and reverse speed ratios for given input speeds and a compound, power-split second electrically variable mode. Torque provided from the power source is added to torque provided from the second motor generator in both forward and reverse electrically variable modes.
