Abstract: A cooling system comprises a liquid storage tank and liquid disposed within the liquid storage tank.

A second heat exchanger is also immersed within the liquid, wherein coolant from a load cooling system flows through the second heat exchanger.

Abstract: An electrical energy recovery, storage, and distribution system that may be used in a vehicle. The system may include a supercapacitor configured to quickly store large amounts of energy. The system may also include multiple circuits operating at different voltage levels, such that an output voltage from the supercapacitor is useful over a larger voltage range and the system is more energy efficient.

Abstract: A stabilizing arrangement of a cooling system module of a vehicle includes stabilizer pins attached to the vehicle cooling system module. Stabilizer slots are incorporated into a component of the chassis of the vehicle, such as a frame extender. The stabilizer slots may be formed as an upwards opening U-shape. Bushings are attached to the stabilizer pins. The stabilizer pins and bushings extend laterally into and engage with the stabilizer slots. Upon installation, the stabilizer pins and bushings are aligned with the stabilizer slots as the cooling system module is lowered onto the ISO mounts. The stabilizer pins and bushings slide vertically downwards into the stabilizer slots as the cooling system module is lowered into place. The simpler stabilizer pins, bushings, and stabilizer slots thereby take the place of expensive, time consuming, complex, labor intensive, and space consuming stay rod arrangements.

Abstract: A vehicle has a waste heat recovery (WHR) system and an engine. The WHR system includes a WHR working fluid circuit with a pump, a power turbine, and a condenser. An engine coolant circuit circulates coolant between the engine and an engine coolant heat exchanger/working fluid boiler in the WHR working fluid circuit. At least one exhaust gas heat exchanger/superheater in the WHR working fluid circuit receives waste heat from an exhaust circuit and/or from an exhaust gas recirculation circuit. A working fluid cooled charge air cooler in the WHR working fluid circuit receives waste heat from compressed charge air in a charge air intake circuit. A recuperator may transfer waste heat from working fluid passing from the power turbine to the condenser to working fluid passing from the working fluid cooled charge air cooler to the engine coolant heat exchanger/working fluid boiler.

Abstract: An engine manages charge air temperature by heating charge air as the engine warms toward normal operating temperature.

Abstract: An EGR cooler core has multiple tubes for conveying engine exhaust gas. Tube inlets are joined to a flat inlet header plate at tube/header plate joints in a flat zone of the inlet header plate. An endless groove in the inlet header plate circumscribes the joints while reducing a constant nominal thickness of the header plate in the flat zone along the groove without creating an opening through the header plate. This gives some compliance to the flat zone for mitigation of stresses induced by tube growth.

Abstract: A method of shutting down an engine determines whether an ignition key is in a first shutdown position. An exhaust gas recirculation valve closes when the ignition key is in the first shutdown position. The engine runs for a predetermined period of time after the exhaust gas recirculation valve is closed. The engine shuts down after running the engine for the predetermined period of time.

Abstract: A three-way throttle valve for an air intake system of an engine comprises an elongate-shaped valve plate, a positioning shaft, and an actuator. The elongate-shaped valve plate is disposed within an intake air portion of an air intake system. The elongate-shaped valve plate has a major axis and a minor axis. The positioning shaft connects to the elongate-shaped valve plate. The positioning shaft is disposed about the minor axis of the elongate-shaped valve plate. The actuator connects to the positioning shaft. The actuator has at least a first position setting, a second position setting, and a third position setting. At least a portion of the elongate-shaped valve plate contacts a portion of the intake air portion of the air intake system when the actuator is disposed in the first position setting.

Abstract: An intake manifold (16) of an internal combustion engine (10) is charged to superatmospheric pressure by operating a first compressor (44) to compress fresh air diluted by exhaust gas into the intake manifold while operating a second compressor (24C) to compress undiluted fresh air into the intake manifold through a device (40) that allows flow in a direction from the second compressor into the intake manifold but not in an opposite direction.

Abstract: A system and method of creating sub-atmospheric and super-atmospheric pressure in an intake manifold (20) of an internal combustion engine (10) that has cylinders (14) within which fuel combusts with air that has entered the cylinders via the intake manifold. A positive displacement airflow control device (26) is disposed upstream of the intake manifold. Sub-atmospheric pressure in the intake manifold is created by applying negative external torque to a shaft (28) of the positive displacement airflow control device and super-atmospheric pressure is created by applying positive external torque to the shaft (28).
