Abstract: A method of operating a fuel tank system in a non-hybrid vehicle is provided. The fuel tank system has a fuel tank, a carbon canister, a canister vent valve, a vapor management valve and an isolation valve fluidly connected between the fuel tank and the carbon canister. The fuel tank system is operated in a pressurized mode wherein the fuel tank is pressurized and the isolation valve is closed. The method determines whether a leak has been detected. The fuel tank system is operated in a non-pressurized mode based on the leak being detected.

Abstract: A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank, a first vent tube, an evaporative emissions control system and a cam driven tank venting control assembly. The first vent tube is disposed in the fuel tank. The evaporative emissions control system is configured to recapture and recycle emitted fuel vapor. The evaporative emissions control system has a controller. The cam driven tank venting control assembly has a rotary actuator that rotates a cam assembly based on operating conditions. The cam assembly has at least a first cam having a first cam profile configured to selectively open and close the first vent tube based on operating conditions.

Abstract: A fill limit vent valve configured for use with a reductant tank includes a valve body, a float and a vapor permeable membrane. The valve body can define an inner chamber and has a valve outlet. The float has a float body configured to be received within the inner chamber and configured to sealingly engage the valve body. The vapor permeable membrane can be configured to permit vapor to pass through while inhibiting liquid from passing through. The float is movable between (i) an open position wherein vapor flows along a first flow path through the valve inner chamber and out of the valve body; and (ii) a closed position wherein the float sealingly engages the valve body and precludes vapor from flowing along the first flow path while allowing flow along a second flow path through the vapor permeable membrane and out of the valve body.

Abstract: An evaporative emissions control system includes a first vent valve configured to selectively open and close a first vent, a second vent valve configured to selectively open and close a second vent, a fuel level sensor configured to sense a fuel level in the fuel tank, a pressure sensor configured to sense a pressure in the fuel tank, an accelerometer configured to measure an acceleration of the vehicle, and a controller configured to regulate operation of the first and second vent valves to provide pressure relief for the fuel tank. The controller is programmed to determine if a refueling event is occurring based one signals indicating the fuel level is increasing, the pressure in the fuel tank is increasing, and the vehicle is not moving, and open at least one of the first and second vent valves based on determining the refueling event is occurring.
