  • Patent number: 12030005
    Abstract: Various example embodiments relate to an automatic drain system for use with a fluid water separator. The automatic drain system includes a liquid-in-fuel sensor configured to detect a liquid level in a water sump. A pump includes an inlet in fluid communication with the water sump and an outlet in fluid communication with the inlet. The pump has an active state and an inactive state. The active state causes the pump to draw liquid in from the inlet and direct liquid toward the outlet. A battery is configured to power the pump. A circuit board is operably connected to the pump and battery. The circuit board includes at least one circuit having a first state and a second state. The first state prevents power flow from the battery to the pump. The second state facilitates power flow from the battery to the pump, transitioning the pump from inactive to active.

  • Patent number: 12018600
    Abstract: A fluid delivery system for an internal combustion engine and a method of monitoring the fluid delivery system are described. The systems and methods monitor and determine various fluid quality parameters and filter element pressure drop, which can be used to determine real-time estimates of remaining useful life for both the filter element and the fluid. The respective remaining useful life calculations are used by the described systems and methods to determine change intervals for the fluid and the filter element. The change intervals can be synchronized by the systems and methods to reduce the amount of down time due to servicing of the fluid delivery system.
