Abstract: A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank and an evaporative emissions control system. The evaporative emissions control system is configured to recapture and recycle emitted fuel vapor. The evaporative emissions control system includes a liquid trap, a first device, a second device, a control module and a G-sensor. The first device is configured to selectively open and close a first vent. The second device is configured to selectively open and close a second vent. The control module regulates operation of the first and second devices to provide over-pressure and vacuum relief for the fuel tank. The G-sensor provides a signal to the control module based on a measured acceleration.

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.

Abstract: An evaporative emissions isolation module system configured to manage venting on a fuel tank system is disclosed. The isolation module system includes a carbon canister, a multi-valve assembly and a controller. The carbon canister is adapted to collect fuel vapor emitted by the fuel tank and to subsequently release the fuel vapor to the engine. The multi-valve assembly includes a motor drive that rotates a camshaft having at least a first cam and a second cam housed in a manifold. The multi-valve assembly has a first valve and a second valve. The first valve selectively fluidly connects the fuel tank and the carbon canister. The second valve fluidly connects the carbon canister with a vent port defined in the manifold that vents to atmosphere. The controller sends signals to the multi-valve assembly based on operating conditions to open and close at least one of the first and second valves.

Abstract: An evaporative emissions control system configured for use with a vehicle fuel tank includes a purge canister, an accelerometer, first and second vent tubes that terminate at first and second vent openings, a first vent valve, a second vent valve, a vent shut-off assembly and a control module. The accelerometer senses acceleration in an x, y and z axis. The first vent valve is fluidly coupled to the first vent tube. The second vent valve is fluidly coupled to the second vent tube. The vent shutoff assembly selectively opens and closes the first and second valves. The control module estimates a location of liquid fuel based on the sensed acceleration from the accelerometer and determines which vent opening is one of submerged and about to be submerged based on the estimated location of the liquid fuel. The control module closes the vent valve associated with the determined vent opening.
