An engine assembly includes an intermittent internal combustion engine having an engine shaft, a turbine having a turbine shaft, an output shaft for driving a load, and a gearbox having a first portion and a second portion. The engine shaft is in engagement with an accessory via the first portion. The turbine shaft is in driving engagement with the output shaft via the second portion. The gearbox is configurable between an engaged and a disengaged configurations. In the disengaged configuration, the first and second portions are decoupled, and the engine shaft and the turbine shaft are rotatable independently from each other. In the engaged configuration, the first and second portions are coupled, and the engine shaft and the turbine shaft are drivingly engaged with each other via the coupled first and second portions.

A hybrid electric vehicle includes a combustion engine, electric machine, turbocharger, and turbo lag reduction assembly that includes an auxiliary compressor and pressure tank, which are coupled to a clutch driven by a driveshaft powered by vehicle wheel rotation. A controller engages the clutch in response to a braking signal, until the auxiliary compressor recharges the pressure tank. The controller also disengages the clutch in response to one of termination of the braking signal and the pressure tank being recharged with compressed air. Additionally, the controller responds to an engine torque demand signal and discharges compressed air from the pressure tank to an intake manifold of the engine. Further, the controller may discharge a volume of compressed air from the pressure tank to the intake manifold of the engine, until a turbo charge limit signal is received that indicates the turbocharger reached an operating speed.

A variable speed hybrid electric supercharger assembly is controlled to regulate an adaptive state of charge of an energy storage device and/or to boost an engine based on a performance mode selected by a driver. In one example, a reference state of charge is determined based upon driving characteristics of a vehicle and compared to an actual state of charge of the energy storage device. If the difference indicates a deficit, an operation mode is selected to regenerate the energy storage device. In another example, a planetary gearing arrangement between an engine and an electric motor is configured to increase or decrease power transferred to the supercharger by the engine based upon the performance mode selected by the driver.

A supercharged internal combustion engine has a supercharger operable to selectively supply a mass of air from below through above atmospheric air pressure according to the operating requirements of the engine. The supercharger has a shuttle combined with a throttle valve that controls the mass of air directed to an air mass bypass opening and supplied to the internal combustion engine. The shuttle has rollers that ride on rails that allow the shuttle to move to open and close the air mass bypass opening in communication with a casing that directs a mass of atmospheric air and a bypass mass of air interfused with the mass of atmospheric air to an air mass inlet of the supercharger.
