Abstract: A system for sensing a fuel level includes sensors that sense the fuel level and a voltage source that applies a constant voltage to the sensors for a predetermined time. The system includes a control module that measures outputs of the sensors at a beginning and at an end of the predetermined time. The control module determines a number of the sensors that are submersed in fuel or air based on the outputs and calculates the fuel level based on the number of the sensors that are submersed in fuel or air.

Abstract: A cap assembly for a wheel including a cup-shaped cap member having a plurality of annular ridges disposed around a circumference thereof, and a retainer ring having a plurality of axially extending flange portions disposed around a circumference thereof. The retainer ring is slidably coupled to the cup-shaped member, the axially extending flange portions are angled relative to a position normal to the ring, and the plurality of axially extending flange portions correspond to the plurality of annular ridges. When the cap assembly is inserted into the wheel, the retainer ring slides along the cup-shaped member and the annular ridges force the axially extending flange portions to the position normal to the ring to attach the flange portions to the wheel.

Abstract: A fuel pump controller includes a detecting device for detecting environmental vibrational energy and converting the environmental vibrational energy into an electrical signal. A motor controller is coupled to a fuel pump motor wherein the electrical signal is used by the controller to command the fuel pump motor to operate at one of a plurality of speeds wherein the commanded speed is at least in part a function of the environmental vibrational energy.

Abstract: A method for actuating an onboard refueling vapor recovery (ORVR) valve to selectively enable passage of fuel vapor from a fuel tank to a collection canister for the fuel vapor. The method includes determining whether a filling event is occurring and determining a fuel level within the fuel tank. The ORVR valve is selectively opened and closed in connection with whether a fueling event occurs and whether the fuel tank is full.

Abstract: An electronic onboard refueling vapor recovery (ORVR) system including an electrically operated ORVR valve that selectively opens and closes a fuel vapor path between a fuel tank and a collection canister. An electronic control circuit generates control signals to selectively open and close the ORVR valve. The electronic control circuit receives one or more inputs from one or a plurality of sensors and evaluates the one or more inputs to determine whether to activate the ORVR valve. The sensor inputs include at least a sensor indicating fuel is being introduced into the filler neck and may also include at least a sensor indicating a fuel level within the tank.

Abstract: A refueling valve for a motor vehicle includes a body connected to the upper wall of a fuel tank in vertical depending relationship. The body has a cover with a vapor exit passage adapted to be connected to a fuel vapor storage canister and a portion depending from the cover that has a vapor exit port that communicates with the fuel tank interior adjacent the upper wall of the fuel tank. A vent tube has one end connected to the vapor exit passage and an opposite end that communicates with the vent exit port and defines a valve seat. The vapor exit port is located with respect to the valve seat so as to separate liquid fuel particles from vapor flow during fuel fill. The valve seat is closed by a float valve when the fuel tank is full.
