A bottoming cycle power system includes a turbo-expander operable to rotate a turbo-crankshaft as a flow of exhaust gas from a combustion process passes through the turbo-expander. A turbo-compressor is operable to compress the flow of exhaust gas after the exhaust gas passes through the turbo-expander. An open cycle absorption chiller system includes an absorber section operable to receive the flow of exhaust gas from the turbo-expander and to mix the flow of exhaust gas with a first refrigerant solution within the absorber section. The first refrigerant solution is operable to absorb water from the exhaust gas as the exhaust gas passes through the first refrigerant solution. The absorber section is operable to route the flow of exhaust gas to the turbo-compressor after the flow of exhaust gas has passed through the first refrigerant solution.

The present invention relates to a kinetic turbopump assembly for a closed loop, in particular of Rankine cycle type, associated with an internal-combustion engine (12) with a drive shaft (26), notably for a motor vehicle, wherein one (10) of the faces of said engine carries accessories (14, 18, 22) of this engine, and at least one winding roller (30, 30′, 30″) for a rotary motion transmission belt (32) connecting at least said accessories to drive shaft (26). According to the invention, the assembly comprises a rotary motion transmission path (T) between shaft (38) of the turbopump and said winding roller.

A low-temperature turbocompressor structural arrangement for an internal combustion engine for using energy that is available but unused during operation to cool the air supplied to the engine by supercharging. The temperature of the air compressed by the compressor is reduced by a cooling system and the air is then conveyed to a further turbine actuated by the intake air flow of the engine. The structural arrangement may be mounted in full or in part, and also each component may be fitted into existing systems.

The invention provides a vehicle engine system, comprising: a hydraulic pump for providing an oil supply during braking; an accumulator configured to: receive the oil supply during braking; store the oil supply under pressure; and release the oil supply under pressure during acceleration; and a turbo charger for receiving the oil supply released under pressure during acceleration.

An adjustment mechanism for an air inlet flow section of a compressor wheel of a turbocharger. The adjustment mechanism defines a variable inlet diameter for an axial air flow to the compressor wheel. The adjustment mechanism has a unison ring and a plurality of vanes. An actuator is used for providing a first pivoting motion to the unison ring about a central axis and thereby providing a second pivoting motion to the plurality of vanes. At least one elastic biaser is arranged, such that it provides, upon the pivoting motion to the unison ring, a restoring force to the unison ring and/or the plurality of vanes. The pivoting motion of the vanes adjusts the inlet diameter of the axial air flow to the compressor wheel.
