    Abstract: A fuel tank system controlled by a control module and constructed in accordance to one example of the present disclosure includes a saddle fuel tank, and a venting assembly. The saddle fuel tank has a first lobe and a second lobe extending on opposite ends of a recessed central portion. The venting assembly comprises a first vent line, a second vent line and a rotary actuator. The first vent line has a first vent port located in the first lobe of the saddle fuel tank near a top portion of the saddle fuel tank above the recessed central portion. The second vent line has a second vent port located in the second lobe of the saddle fuel tank near a top portion of the saddle fuel tank above the recessed central portion.

    Abstract: A vent shut-off assembly configured to manage venting on a fuel tank configured to deliver fuel to an internal combustion engine includes a main housing, a poppet valve and an actuator. The main housing is positioned outside of the fuel tank and selectively vents to a canister. The poppet valve is disposed in the main housing and includes a plunger that provides over pressure relief (OPR) and over vacuum relief (OVR) functions. The actuator assembly can be housed in the main housing and includes a cam assembly having a cam shaft that includes a cam having a profile that one of opens and closes the poppet valve. When the poppet valve is in the closed position, vapor is precluded from passing between the fuel tank and the canister. When the poppet vale is in the open position, vapor is permitted from passing between the fuel tank and the canister.

    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.
