    Abstract: An engine cooling system comprises an engine cooling circuit, comprising a first pump structured to circulate engine coolant fluid therethrough. A remote coolant radiator positioned along the engine cooling circuit downstream of the engine and outside of a vehicle cooling package area is structured to transfer heat from the engine coolant fluid to air. A coolant heat exchanger is positioned along the engine cooling circuit in parallel to the remote coolant radiator. A waste heat recovery system comprises a working fluid circuit comprising a second pump. The coolant heat exchanger is positioned along the working fluid circuit and is structured to transfer heat from the engine coolant fluid to the working fluid. An expander is structured to convert energy from the heat transferred to the working fluid from the engine cooling fluid to mechanical energy. A condenser positioned downstream of the expander is structured to cool the working fluid.

    Abstract: Methods and systems implementing hybrid vehicle with multi-mode functionality are provided. The vehicle includes a steerable front axle coupled with a first motive power source having an integrated axle including an electric motor and a transmission. A rear axle is coupled with a second motive power source and separately operable from the steerable front axle. A sensor measures an additional load applied on the vehicle. A controller coupled with the sensor, the first motive power source, and the second motive power source. The controller receives measurement data from the sensor; selects, based on the measurement data, (a) a first operation mode of activating only the first motive power source or (b) a second operation mode of activating only the second motive power source, to operate the vehicle; and activates, based on the first operation mode or the second operation mode that is selected, the first motive power source or the second motive power source to operate the vehicle.

    Abstract: An engine waste heat recovery (WHR) system includes a turbocharger WHR portion, an exhaust WHR portion, an expander in the exhaust WHR portion, a condenser, valves, and a controller. The expander receives a working fluid in a superheated form and converts thermal energy in the working fluid into mechanical energy or electrical energy. The condenser condenses the working fluid for recirculation through the engine WHR system. The recuperator is fluidly coupled between the expander and the condenser to allow the working fluid to flow from the expander to the condenser. The recuperator transfers thermal energy to a flow of the working fluid from the turbocharger WHR portion. Each valve is fluidly coupled to one of the turbocharger WHR portion and the exhaust WHR portion. The controller is electrically coupled to the valves, and the controller selectively controls the valves to selectively circulate the working fluid through the engine WHR system.

    Abstract: A waste heat recovery system includes a first heat exchanger, a second heat exchanger, and an expander. The first heat exchanger receives working fluid from a first portion of a first loop and provides the working fluid to a second portion of the first loop. The second heat exchanger receives the working fluid from a first portion of a second loop and provides the working fluid to a second portion of the second loop. The expander provides the working fluid to a first portion of a common line. The expander includes a stator. The stator includes a first inlet and a second inlet. The common line provides the working fluid to both the first loop and the second loop upstream of the first portion of the first loop and upstream of the first portion of the second loop.
