摘要： A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to: while controlling the bypass valve to direct exhaust gas to the PNA, detect a torque demand that is greater than a threshold value; responsive to detecting that the torque demand is greater than the threshold value, engage a motor, coupled with a battery system, with a drive shaft of the system to meet at least a portion of the torque demand; in response to the engagement of the motor with the drive shaft not meeting all of the torque demand, engage the engine with the drive shaft to meet a remainder of the torque demand.

摘要： A fuel selector for use with a dual fuel generator includes a selector plate, a first fuel valve assembly positioned adjacent the selector plate and actuatable between an ON position and an OFF position to selectively control a first fuel flow to an engine of the dual fuel generator, and a second fuel valve assembly positioned adjacent the selector plate and actuatable between an ON position and an OFF position to selectively control a second fuel flow to the engine of the dual fuel generator. A selector switch coupled to the selector plate is linearly translatable from a first position to a second position, so as to enable positioning of only one of the first fuel valve assembly and the second fuel valve assembly in the ON position at a given time, such that the first and second fuel valve assemblies cannot be in the ON position concurrently.

摘要： Method and apparatus for adaptively adjusting the storage of fuels for use in a fuel blending process. First and second fuels are stored in storage vessels at an initial volumetric fuel storage ratio. A storage controller executes a performance strategy to adaptively adjust at least one storage parameter in response to a predicted or detected change in operating conditions of the system. The performance strategy can include increasing a storage pressure of at least one of the fuels and/or changing a total number of storage vessels used to store the respective fuels. A dispensing mechanism transfers a blended fuel formed from the first and second fuels in accordance with the execution of the performance strategy. The fuels can take a variety of forms including hydrogen (H2), oxygen (O2), hydrocarbons, etc. The blended fuel may be dispensed by a fueling station to a motor vehicle.

摘要： Provided is a device configured to determine a power capacity of a battery of a vehicle, predict a first set of values indicative of amounts of power to be stored during a time interval by the battery, the power being generated by a renewable energy generator carried by the vehicle, and predict a second set of values indicative of amounts of energy to be consumed from the battery during the time interval based on previous energy consumption by the vehicle. The device is also configured to determine a score based on the power capacity, the first set of values, and the second set of values. The system is also configured to determine whether the score satisfies a threshold and, in response to a determination that the score satisfies the threshold, activate an internal combustion engine to charge to the battery.

摘要： A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

摘要： A generator set configured to provide an electrical output to an external electrical load. The generator set includes an engine configured to drive an electric generator, the engine including an engine block, where the electric generator is configured to couple to the external electrical load. The generator set includes a heating system in fluid communication with the engine block, the heating system including an electric fluid heater, where the electric jacket fluid includes a resistive load configured to supplement the external electrical load. The generator set includes a control system for: monitoring a first parameter of the engine; generating a first control signal in response to the first parameter being less than a first threshold; and increasing the external electrical load by turning on the electric fluid heater in response to the first control signal.
