  • Publication number: 20230271495
    Abstract: A fuel system for a vehicle includes a fuel tank configured to provide fuel to an engine of the vehicle, a shutoff valve configured to selectively restrict a flow of the fuel along a flow path between the fuel tank and the engine, a temperature sensor configured to monitor a temperature of at least one of the engine of the vehicle or a temperature associated with a body area of the vehicle and provide a temperature signal, and a controller coupled to the temperature sensor and the shutoff valve. The controller is configured to control the shutoff valve to restrict the flow of the fuel in response to the temperature signal indicating a temperature in excess of a temperature threshold.

  • Patent number: 11679669
    Abstract: A refuse vehicle includes a chassis having a prime mover, a body assembly coupled to the chassis, a tailgate pivotally coupled to the body assembly, an energy storage device coupled to the tailgate and moveable therewith, at least one of a non-structural conduit, a non-structural raceway, and a non-structural channel configured to contain at least one of wiring and a hydraulic line, and an impact mitigation system including at least one frame member positioned to direct impact loads around the energy storage device. The prime mover is configured to be powered by the energy storage device. The impact mitigation system provides a protected region within which the energy storage device is disposed.
