Definitions
- the present invention relates generally to vehicle fuel tanks and, more particularly, to an assembly for eliminating unwanted fuel vapor emissions from vehicle fuel tanks
- hydrocarbon fuel vapor One source of hydrocarbon fuel vapor is the fuel tanks of vehicles using gasoline or other hydrocarbon fuels with high volatility The fuel vapor can escape to the atmosphere du ⁇ ng the filling of the tanks and usually even after the tanks are filled
- Current production motor vehicles include a fuel storage tank to hold gasoline, a pump module to send liquid fuel to the engine and measure the quantity of fuel remaining and a carbon-filled canister to catch and hold hydrocarbon vapor that would otherwise evaporate from the fuel tank out into the environment
- the canister contains activated charcoal that captures fuel vapor formed m the fuel tank through a vapor tube and valve assembly mounted in the top of the tank.
- the canister also communicates with the intake manifold of the vehicle engine to exhaust fuel vapor stored in the canister to the manifold for combustion du ⁇ ng operation of the engine.
- the valve assembly usually has a level responsive valve that enables the valve to stay open at a sufficiently low fuel level to permit fuel vapor to flow freely from the fuel tank into the canister.
- Du ⁇ ng refueling as the fuel level ⁇ ses to approach a desired maximum level of fuel in the tank, a float may be raised to close the level responsive valve to prevent liquid fuel from flowing into the vapor receiving canister [005]
- the use of such onboard vapor recovery systems to remove excess fuel vapor from the fuel tank is one solution to the environmental problem.
- conventional systems are capable of greatly reducing the amount of vapor released to the environment. For example, such systems may be produced from which less than 0.5 grams of vapor will escape du ⁇ ng the U S. EPA and California Air Resource Board 3-day test.
- emerging environmental regulations require further reductions in the amount of fuel vapor emissions
- a zero emissions fuel system includes a fuel tank fluidly interconnected with a fuel vapor containment and abso ⁇ tion canister.
- the canister is further interconnected with an engine intake manifold via a purge solenoid valve that controls the extent to which a vacuum in the intake manifold affects the canister.
- the canister is also interconnected with the ambient environment via a vacuum relief valve and a refueling vent solenoid valve
- the purge solenoid valve valve controlled by an electronic control module, opens a predetermined amount in response to engine demand, thereby allowing a vacuum m the intake manifold to draw vapor from the canister for consumption by the engine
- the vacuum relief valve is drawn open, thereby allowing outside air to flow into the system through the vacuum relief valve to facilitate purging of the canister
- the vacuum relief valve closes. Since the fuel tank is in fluid communication with the canister, the canister and the fuel tank are always at the same pressure.
- the purge solenoid valve closes when the fuel mix in the intake manifold is too rich or if the intake manifold vacuum is insufficient to maintain vacuum in the tank and canister
- a pressure relief valve connected to the canister operates to vent the fuel tank and canister if positive pressure ⁇ ses above a predetermined setpoint due to extreme operating conditions.
- the vacuum relief and the pressure relief valves may be eliminated by electronically controlling the refueling vent solenoid valve between open and closed positions in response to predetermined pressure conditions
- the refueling vent solenoid would open all of the way for refueling, but may be opened only a little while the vehicle is running in response to a predetermined vacuum pressure or positive pressure.
- a control loop may control the extent to which the vent solenoid opens and closes.
- the canister and the fuel tank are always at the same pressure, only one pressure sensing device need be utilized. Further, the canister is continuously connected with the tank such that it may absorb fuel vapor at any time, and is not limited to only absorbing vapor during fuel filling operation. The complexity of the system is reduced by eliminating several valves and conduits, thereby further reducing the cost of the system as well
- FIG. 1 is a diagrammatic view of a first embodiment of a vacuum based fuel system according to the present invention
- FIG. 2 is a diagrammatic view of a second embodiment of the vacuum based fuel system according to the present invention.
- Fuel system 10 includes a fuel tank 12 that contains a fuel pump module 14 adapted to deliver fuel to the engine 38 and a device 16, such as a float, to measure fuel quantity Tank 12 is connected to a canister 18 that receives, contains and stores fuel vapor that evaporates from the liquid fuel contained in tank 12
- canister 18 may be entirely located with fuel tank 12
- canister 18 may also be placed at a convenient location remote from fuel tank 12
- canister 18 will be desc ⁇ bed as being located withm the tank 12
- tank 12, pump module 14 and canister 18 may be conventionally available parts
- tank 12 may be formed of any ⁇ gid mate ⁇ al, such as plastic
- tank 12 is preferably formed with measures to prevent permeation of fuel through the tank walls
- a vapor tube 28 fluidly connects tank 12 to canister 18 Additionally, vapor tube 28 may include a fuel fill-hmitmg valve 20 to prevent liquid fuel from flowing into canister 18 du ⁇ ng refueling operations
- a pressure sensor 22 is placed to sense the pressure within either the fuel tank or the canister Since pressure withm the fuel tank and canister is approximately equal, only one pressure sensor 22 is required
- Pressure sensor 22 may be a relative sensor, with one side referencing outside ambient pressure (as shown m Figure 1), or may be an absolute pressure sensor placed completely withm the tank Pressure sensor 22 may therefore be placed in any convenient location, including on the vent pipe 24 of camster 18 to sense system pressure
- Fuel tank 12 may also include a remote grade vent 26 attached to the vapor tube 28 upstream of the fuel fill limiting valve 20 and canister 18 Grade vent 26 ensures that only air and vapor are drawn into vapor tube 28 to camster 18, and not liquid fuel, at any attitude or fuel level reasonably expected
- a purge tube 30 fluidly interconnects canister 18 to an engine intake manifold 32 Flow of vapor from canister 18 to manifold 32 is controlled by a purge solenoid valve 34 that is controlled by an engine control module (ECM) 36 Intake manifold 32 is connected to engine 38 such that any fuel vapor flowing through purge tube 30 is drawn into the engine and combusted
- ECM engine control module
- Intake manifold 32 is connected to engine 38 such that any fuel vapor flowing through purge tube 30 is drawn into the engine and combusted
- the vent pipe 24 terminates in a series of valves designed to both ensure vacuum pressure within canister 18 and to prevent extreme pressure conditions within both canister 18 and fuel tank 12
- Vent pipe 24 terminates in
- ECM 36 may close purge solenoid valve 34, thereby sealing canister 18 Thereafter, if pressure within canister 18 and fuel tank 12 exceeds a predetermined set point, over pressure relief valve 42 may open to relieve the pressure within canister 18 and tank 12 Similarly, when engine 38 is laboring (such as under heavy load), pressure within intake manifold 32 may exceed the pressure in tank 12 and in canister 18 In such a case, ECM 36 would also close solenoid 34 to prevent reverse flow through purge tube 30 back into canister 18 Finally, when engine 38 is not operating, all valves are closed If pressure within canister 18 and in tank 12 undergoes a large change, either over pressure relief valve 42 or vacuum relief valve 44 will open
- Fuel filler vent valve 40 opens only in response to an indication by the vehicle operator that refueling is about to take place When open, fuel filler vent valve 40 allows air and vapor from withm the fuel tank to flow through ⁇ apor tube 28 and into canister 18 As the combined fuel vapor and air flow through canister 18, the fuel vapor is entrained withm the canister, thereby allowing onlv air to exhaust through vent pipe 24 to ambient Thus, liquid fuel is allowed to displace vapor from the tank 12 du ⁇ ng refueling operation [0020] A second embodiment of the vacuum based fuel system 1 10 is shown diagrammatically in Figure 2 A.
- purge solenoid valve 134 connected to intake manifold 132 is controlled by an electronic control module (not shown) to meter fuel vapor from the fuel tank 1 12 and canister 1 18 through purge tube 130
- a normallv closed refueling ⁇ ent solenoid 140 blocks ambient air from ente ⁇ ng (or leaving) canister 1 18 through v ent pipe 124
- the reluehng vent solenoid 140 is only opened to allow air to escape the fuel tank 1 12 as liquid fuel is received therein
- a vacuum relief valv e 144 is drawn open when the tank reaches the desired le el of vacuum, in which case air flow s inwardK through the relief valv e 144 and v ent pipe 124 to purge the canister 1 18
- the electronic control module w close the purge solenoid valve 134 if the fuel mix in the engine is too rich or if intake manifold 132 cuum is insufficient to maintain vacuum in the tank 1 12 and canister 1 18 A.s abov
- the vacuum relief valv e 144 of Figure 2 may be eliminated by electronically controlling the position of the refueling vent solenoid valve 140 Under such conditions, the refueling vent solenoid valv e 140 would be opened all the way for refueling, but would only open a relatively small amount while the vehicle is running in response to over- or under-pressure conditions. The extent to which refueling vent solenoid valve 140 opens would then be continuously controlled by the electronic control module through feedback on fuel tank 112 pressure.
- the present invention thus uses the vacuum of the engine to pull a vacuum on both the fuel tank and canister.
- the canister is not isolated from the fuel tank during vehicle operation. Instead, purging of the tank and canister may occur at all times during vehicle operation without allowing any environmental release of fuel vapor.
- purging of the canister is enhanced, and the canister contains less fuel vapor after engine operation than existing vacuum fuel systems.
- a conventional purge solenoid valve controls canister purge so that fuel mixture at the engine is correct for clean emissions. Further, by adding a new pressure sensing device to the fuel system, vacuum within the system may be controlled by actuation of the purge solenoid valve and the ECM.
- a relief valve at the clean air inlet of the canister then easily controls the level of vacuum in the fuel system.
- an electrically driven valve (such as a PWM driven solenoid) can be added to the system and be driven in response to the measured system pressure. In both cases, the canister spends most of its time at a vacuum, thereby improves purgeability while still preventing fuel vapor release to the environment.
