  • Patent number: 11768128
    Abstract: An internal combustion engine for neutron diffraction analysis is provided. The engine includes an elongated piston chamber formed from an aluminum alloy to ensure maximum neutron visibility into the combustion chamber. An elongated piston assembly reciprocates within the elongated piston chamber, the piston assembly including an upper piston joined to a lower piston. The upper piston and the lower piston are hollow, thereby reducing the reciprocating mass and increasing neutron access to the combustion chamber. The upper piston is lubricated with a neutron-transparent fluorocarbon lubricant such as perfluoropolyether (PFPE), while the lower piston and the crankcase are lubricated with hydrocarbon lubricant. The engine enables 3D and time-resolved measurements of strain, stress, and temperature, as well as phase transformation, texture, and microstructure.

  • Patent number: 10987993
    Abstract: A vehicle thermal management system including an engine, a vehicle cabin, a transmission thermal loop, and a controller is provided. The transmission thermal loop may include a transmission assembly in operational communication with the engine and a cabin thermal loop. The controller may be programmed to, responsive to detection of an engine off condition, output to a shut-off valve an open command such that heat from the transmission thermal loop transfers to the cabin thermal loop to warm the vehicle cabin. The controller may be further programmed to, responsive to detection of a cabin heater core having a temperature above a predetermined threshold, output a command to a coolant heater of an engine thermal loop to direct warm or cold fluid to the transmission assembly based on a detected transmission thermal loop temperature.

  • Patent number: 10953864
    Abstract: Methods and systems are provided for improving the operating range of an electric vehicle having an engine wherein waste heat generated during motor operation is transferred to pre-heat the engine. Engine starting is predicted based on the electrical torque demand of the vehicle relative to the actual and predicted electrical energy consumption of the electric vehicle. Prior to starting the engine to charge a battery of the motor, various engine components are pre-heated in an order that improves vehicle range while also optimizing fuel economy.
