Description
Technical field
The present invention relates to a kind of fuel vapour storage and recovery plant, for reducing the discharge vaporization from motor vehicle.In recent years, the fuel vapour storage and the recovery plant that include fuel vapour storage tank are well known in the prior art.The Fuel Petroleum using in many internal-combustion engines is very volatile.It is mainly the discharge vaporization that occurs fuel vapour due to the ventilation of vehicle fuel tank in the vehicle with internal-combustion engine.In the time of storing cycle, the variation of temperature or pressure makes to be loaded with from the hydrocarbon of fuel tank effusion in air.Some fuel must be evaporated in the air in fuel tank, form thus the form of steam.If allowed from the not treated atmosphere that just flows into of air of fuel tank discharge, this air must carry fuel vapour so.Can discharge how many fuel vapour government about vehicle fuel system and surely have regulations.
Background technique
Conventionally, in order to prevent that fuel vapour is lost in atmosphere, the fuel tank of automobile is discharged in canister by pipe ventilated, and this canister accommodates suitable fuel sorbing material, for example active carbon.The active carbon particle of high surface area is widely used, and temporarily absorbs fuel vapour.
In the time that vehicle shuts down for a long time and when vehicle, refuel and when the air that is loaded with steam discharges (discharge refuels) from fuel tank, the fuel vapour storage and the recovery plant that include fuel vapour storage tank (so-called canister) must be tackled fuel vapour discharge.
In the fuel recovery system for European market, because the discharge that refuels is not generally discharged by canister, conventionally do not play an important role so refuel to discharge.But in fuel vapour storage and the reclaiming system of the one for North America market, these discharges that refuel are still discharged by canister.
Due to the characteristic of sorbent in canister, obviously canister has limited loading.Conventionally wish that canister has high carbon displacement volume, but, for purpose of design, also wish that canister has less volume.Always there is enough carbon displacement volumes in order to ensure canister, the in the situation that of internal combustion engine operation, conventionally apply certain negative pressure from the gas handling system of motor to the inside of tank by the fuel vapour outlet of canister.Like this, make atmospheric air enter canister by atmospheric air import, to absorb the fuel vapour of (pick up) trapping, and export the intake manifold that this fuel vapour is carried into the gas handling system of motor by fuel vapour.During this tank desorption (purge) pattern, the fuel vapour being stored in canister burns in internal-combustion engine.
Although the storage of modern fuels steam and reclaiming system are very effective, still can allow residual hydrocarbon emission in atmosphere.Especially when there is high hydrocarbon concentration gradient between the atmosphere ventilated port of canister and sorbent time, promote these so-called " discharge (bleed emission) of escaping " (breathing loss/DBL between daytime) by diffusion.In the time can reducing hydrocarbon concentration gradient, can reduce significantly the discharge of escaping.This can realize by the displacement volume that increases canister obviously.
But, also should be clear, be stored in hydrocarbon in canister and only only have certain percentage can be by desorption or discharge effectively during desorption.This is a problem for time that can only be limited for carrying out for the automobile of desorption, for example, and the electricity hybrid vehicle (electro hybrid car) that the operation mode of internal-combustion engine is shorter.
Use the so-called fuel flexible that comprises a large amount of ethanol (flexi fuel) to have another problem.Ethanol is high-volatile fuel, has higher vapor pressure.For example, on market, so-called E10 fuel (10% ethanol) has the highest steam generation at present.This means that the amount of fuel vapor that canister absorbs from fuel tank is high.On the other hand, during the normal desorption pattern of traditional canister, only only have the fuel vapour uptake of certain percentage to be discharged from.As a result, exhaust quickly the fuel vapour capacity of common canister.Then, the escape of full load canister discharge increases to the degree of the discharge value that exceedes legal provisions conventionally.
In order to improve the desorption eliminating rate during desorption pattern, steam storage and the recovering device of the so-called desorption heater of several uses proposed.Enter the atmospheric air in tank by heating via atmospheric air import, strengthen significantly the efficiency of removing the hydrocarbon trapping in the micropore of sorbent.
For example, US6,230,693B1 discloses a kind of evaporative emission control system, and it is for by providing auxiliary tank to reduce the amount of fuel vapor from vehicular discharge, operates together with the storage tank of this auxiliary tank and evaporative emission control system.This storage tank comprises the first sorbing material and has the ventilated port being communicated with this first sorbing material.Auxiliary tank comprises closure member, the first and second passages, heater and connector.In closure member inner side, the second sorbing material contacts completely with heater.In the regeneration stage of the operation of control system, heater can be used for heating the desorption air of the second sorbing material and process.This makes the second and first sorbing material can be released in more easily the fuel vapour absorbing during the memory phase before of this operation, and this fuel vapour can be burnt between main combustion period.
In addition,, according to US6, the storage tank of 230,693 evaporative emission control system comprises two fuel vapour storage compartment that connect side by side by flow channel.Particularly, in fact separating of tank mean flow restriction.Because it is very low to flow through the driving pressure of tank, be that important design is considered so flow restriction is kept to minimum.
Summary of the invention
The object of the present invention is to provide a kind of fuel vapour storage and recovery plant that includes fuel vapour storage tank, it has carried out further improvement for so-called escape discharge, namely has breathing loss efficiency between improved daytime.Another object of the present invention is to provide a kind of fuel vapour storage and recovery plant that includes fuel vapour storage tank, and it has comparatively compact design and lower carbon volume, and has high displacement volume.
Realize the object of these and other by including the fuel vapour storage of fuel vapour storage tank and recovery plant, described fuel reservoir tank at least comprises the first steam storage compartment and the second steam storage compartment with sorbing material, steam inlet, atmosphere ventilated port and desorption mouth, described fuel vapour storage tank defines the inlet air flow path between inlet air flow path and described atmosphere ventilated port and the described desorption mouth between described steam inlet and described atmosphere ventilated port, wherein, described the first steam storage compartment and described the second steam storage compartment are separated by air clearance diffusion barrier each other along flow direction.
