Embodiment Construction

[0051] Figure 1A A first embodiment of the fuel vapor recovery system of the present invention is shown. The system comprises: a valve 10 , 20 , 30 , an actuator 15 , 25 , 35 for operating said valve 10 , 20 , 30 , and a controller 50 for controlling the actuator 15 , 25 , 35 . The valve 10 is arranged in line between the vapor outlet 61 of the vehicle tank 60 and the tank inlet 81 of the tank 80 and the valve 20 is arranged between the purge outlet 83 of the tank 80 and the engine 70 . The valve 30 is arranged between the vapor outlet 61 of the vehicle tank and the atmosphere 90 , and more particularly between the tank outlet 82 and the atmosphere 90 . Thus, both valves 10 and 30 are arranged in line between the vapor outlet 61 and the atmosphere 90 .

[0052] The valve 10 is configured to be positionable in a closed position, an open position producing a passageway having a first size, and one or more intermediate positions, each of said intermediate positions producing a ...

Abstract

The present invention proposes a vapor recovery system for recovering vapors from a vehicle tank, the system comprising: - a valve (10) configured to be positionable in a closed position, creating an opening of a passageway having a first dimension position and one or more intermediate positions, each of which produces a passage having a size smaller than the first size; an actuator (15) configured to operate the valve ;- An electronic controller (50) configured to control the actuator to position the valve in a sequence of positions over time. The sequence of positions includes one or more of the intermediate positions during a time period (T). The valve is arranged in a line of the vapor recovery system between a vapor outlet of the vehicle tank and the atmosphere.

Description

technical field [0001] Embodiments of the invention relate to the field of vehicle storage systems with vapor control and vapor control methods. More generally, the invention relates to the field of conventional vehicles and hybrid vehicles. Background technique [0002] Due to increased emission standards, vehicles today often include fuel vapor recovery systems. Such a fuel vapor recovery system includes a canister for receiving fuel vapor generated in a fuel tank. Fuel vapor absorbent material located in the canister retains fuel vapors as they are drained from the fuel tank, such as during refueling. During engine operation, fuel vapors contained in the canister may be purged by drawing fresh air through the canister. In the prior art fuel vapor recovery system, a vapor vent valve (vapourvent valve) is usually provided between the inlet of the canister and the storage tank to prevent the vapor from the fuel storage tank from entering the canister. Furthermore, a tank...
