Abstract: A dual-fluid receptacle for a diesel vehicle includes an outer wall disposed on an outer surface of the vehicle. The outer wall defines a diesel receptacle for receiving diesel fuel, a diesel-exhaust receptacle adjacent the diesel receptacle for receiving a diesel-exhaust fluid, and a bridge portion disposed between the diesel and diesel-exhaust receptacles. The receptacles are configured to simultaneously receive the diesel fuel and diesel-exhaust fluid from a single fluid dispensing unit. This allows an operator to fill the vehicle with diesel fuel and diesel-exhaust fluid, simultaneously, from a single fluid dispensing unit. A projection extends from the outer wall proximate to at least one of the two receptacles. The projection is configured to cooperate with an engagement feature of the fluid dispensing unit to selectively enable dispensing of diesel.

Abstract: An air-conditioning system which may be included in a motor vehicle may include a single pair of tube-and-plate heat exchangers arranged within a common vacuum enclosure, the heat exchangers selectively coupled with a heat source, a radiator, and an air-conditioning core.

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.
