Abstract: A thermal operated fluid pump has a plunger which is moved by a thermally expandable element to compress a fluid, such as natural gas, into a storage cylinder.

Abstract: An Electric Tag Axle has a differential connected to two axle shafts. A two speed gearbox is connected to the differential by way of a ring and pinion gear. A longitudinally arranged electric motor/generator is connected to the two speed gearbox. A single wheel disconnect mechanism within the axle allows for neutral operation by allowing the differential to freewheel. A vehicle energy management system is connected to the Electric Tag Axle and to a traction battery pack, and is configured to operate the Electric Tag Axle in a low range motoring mode, a high range motoring mode, a regenerative braking mode, and in the neutral mode. This allows the Electric Tag Axle are able to efficiently make use of a limited amount of stored electrical energy during vehicle takeoff, while efficiently supplementing propulsion power during motoring at cruise speeds, and while efficiently recapturing kinetic energy during regenerative braking.

Abstract: A vehicle climate control system has a control strategy which controls temperature of an evaporator in a refrigeration circuit to achieve a target temperature/relative humidity within a comfort zone which is defined by upper and lower temperature boundaries and upper and lower relative humidity boundaries. Several system embodiments are disclosed, including an all-electric system. All systems operate with improved efficiency.

Abstract: An exhaust aftertreatment interface comprises aftertreatment device assembly and first and second mounting brackets attached to the aftertreatment device assembly. First and second apertures are disposed on the mounting brackets. First and second bushings are disposed in the apertures. A fastener is disposed through the bushings.

Abstract: In a truck vehicle, a controller controls a mechanism to apportion the sum total of weight borne by a tandem axle between a drive axle and a tag axle.
