Summary:

Generally Hybrid Electrical Vehicles (HEV's) tend to have difficulty with regard to evaporative emissions because they have less capability of purging canisters compared with that of conventional systems. Toyota has developed a new fuel system that can address this difficulty and enables outstanding performance for the new-generation HEV. The fuel system, called the "Fuel Vapor-containment System (FVS)", consists of newly developed or redesigned components, such as a high strength fuel tank, a Fuel Vapor-containment Valve (FVV), refueling canister and a purge buffer as well as newly defined controls of the components for the vehicle. The fuel tank is sealed while a vehicle is parked and fuel vapor does not flow into the canister by control of the FVV, except during refueling events. Therefore, HEV's do not have to ensure as much as purge capacity to achieve the necessary lower evaporative requirements. As a result, an HEV can provide low fuel consumption and environmental-friendliness which meets Super Ultra Low Emission Vehicle (SULEV) exhaust emissions requirements and zero evaporative emissions standards in California
