Abstract: An engine is described having an engine control unit and two or more hydraulically operated wheels, wherein a fluid is flowed from an accumulator to the engine via the first wheel to assist in acceleration of the turbocharger in response to an acceleration signal from the engine control system and wherein the fluid is flowed from the engine to the accumulator via the second wheel to decelerate the turbocharger in response to a deceleration signal from the engine control unit. In one particular embodiment, the second wheel absorbs energy from the turbocharger in response to the deceleration signal from the engine control unit to decelerate the turbocharger. In some embodiments, the hydraulically operated wheels may be positioned on the same shaft of, and between, the turbine and compressor of the turbocharger.

Abstract: A vehicle climate control system includes a thermal-adsorption heat pump driven by engine exhaust heat, the heat pump including two adsorbers asynchronously switching between adsorbing and desorbing modes, each adsorber coupled with a corresponding antifreeze tank via a plurality of refrigerant-containing wick chambers. Cold heat transfer fluid (HTF) flows through the adsorber during the adsorbing mode which causes evaporation of refrigerant from the wick chambers, thereby cooling antifreeze, whereas hot HTF flows through the adsorber during the desorbing mode which causes condensation of refrigerant at the wick chambers, thereby heating antifreeze. In this way, the thermal-adsorption heat pump may condition cabin air independent of engine coolant and without exerting a load on the engine.

An original query is received from a client. One or more segments in the original query are identified including an anchor segment and zero or more remaining segments. The anchor segment is identified based on cursor placement within the original query. Then one or more sibling segments associated with the anchor segment are identified. The sibling segments are identified by the server system to be semantically distinct from anchor segment. Then one or more query refinement candidates are identified. A respective query refinement candidate includes a sibling segment in place of the anchor segment and includes the remaining segments, if any, of the original query. Then information including one or more of the query refinement candidates is sent to the client for presentation.
