The utility model is a kind of control recovering device of automotive fuel noxious emission.
The petrol tank of automobile and the float chamber of Carburetor often have the gasoline vapor (HC) of volatilization, are dissipated in the atmosphere by the channel that is communicated with the external world.The result causes pollution of atmosphere and wastes energy.When HC value in the air surpasses 10 mg/litre, can cause human various diseases according to statistics, just can cause death in one hour when surpassing 30 mg/litre.Therefore, this part gasoline is reclaimed and the problem effectively utilized has been subjected to attention abroad.The U.S. is from the seventies, and for the protection urban environment is just clearly stipulated: the automobile of going down town must take measures to control the volatilization of this gasoline vapor.Japan has also taked relative measures from early eighties.But this class control gear all is and the automobile accessories of finalizing the design that assembling is dispatched from the factory together, therefore reequips or be transplanted on other vehicles all very difficult.And cost is very high.China is current also not to take measure that the automobile gasoline discharge of steam is limited, so auto manufacturing and imported auto are not all installed this class control gear yet.But because urban atmospheric pollution is on the rise, caused the attention of relevant department in recent years.In 1985 Beijing Environmental Protection Agency and Beijing carrier cooperation research and development one cover gasoline evaporation recovering device, it can reclaim control to the evaporation of gasoline in the fuel tank, but reequips cumbersome.From present existing all kinds of recovery control devices, major part can only be controlled the recovery of gasoline vapor in the fuel tank, and can not reclaim gasoline vapor in the Carburetor, even the device that has can reclaim the gasoline vapor in the Carburetor, also can only play partially recycled purpose.
Problem at above-mentioned prior art existence, the purpose of this utility model is that design a kind ofly can all be controlled recovery with the gasoline evaporation loss of fuel tank and carburetor bowl, can be applicable to existing various vehicle hot-rod gasoline evaporation control recovering devices again easily.
Automobile gasoline evaporation control recovering device of the present utility model, be by playing the adsorbing charcoal jar (3) that evenly is filled with the granular active carbon grain, the bi-bit bi-pass desorption valve (7) that starts to control adsorbing two-position three way absorption valve (4) of system carburetor bowl (5) interior gasoline vapor and the interior gasoline vapor desorption of control carburetor bowl (5) has reached recovery control section and the oily vapour connecting pipeline that the pressure vacuum valve (2) of controlling the middle gasoline vapor recovery effect of fuel tank (1) formed and has constituted.
Described embodiment is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is fundamental diagram of the present utility model
Accompanying drawing 2 is fuel tank cap component diagram of the present utility model
Accompanying drawing 3 is overall erection drawing of the present utility model
Evenly being filled with particle diameter in the charcoal jar (3) of this model utility device is 10～20 purpose activated carbon grains.Charcoal jar (3) has oily steam pipe road to be connected with atmosphere and control section.Starting to control system carburetor bowl (5) interior gasoline vapor reclaims adsorbing two-position three way and adsorbs valve (4) and have oily steam pipe road to be connected with charcoal jar (3), carburetor bowl (5), air-strainer (8) three places, in the absorption valve (4) opening/shutting valve is housed, by the keying of ignition switch control valve.When motor cut-offs flame-out quitting work, valve open in absorption valve (4) passage of carburetor bowl (5) with charcoal jar (3), the gasoline of being deposited in carburetor bowl this moment (5), because of the body high temperature of motor turns to gasoline vapor, and through absorption valve (4), oily steam pipe road and flowing in the charcoal jar (3).Because of active carbon has the characteristic of absorption to gas phase, thereby reach the purpose that reclaims gasoline vapor.After engine start, automobile is started working, adsorb valve (4) this moment and closed passage between carburetor bowl (5) and the charcoal jar (3), just stopped suction-operated, also opened simultaneously the passage between fuel bowl (5) and the air-strainer (8), thereby guaranteed that the working pressure in the carburetor bowl (5) is constant.At this moment the gasoline vapor in the float chamber (5) is brought in the firing chamber through suction tude.Form closed state owing to having adopted two-position three way absorption valve (4) that the original balance of carburetor bowl (5) duct is stopped up, so overcome the problem that former bi-bit bi-pass absorption valve can not reach the interior gasoline vapor of whole recovery carburetor bowls (5).
When galloping, the active carbon layer of air stream by charcoal jar (3), this moment, the gasoline vapor molecule ran into ozone stream, will break away from active carbon layer and with air stream outflow charcoal jar (3), this phenomenon is known as desorption.Active carbon in charcoal jar this moment (3) is reproduced.By accelerator pedal interlock control or control automatically, make the valve opening of desorption valve (7), open the passage of charcoal jar (3) and carburetor air pipe (6), make the gasoline vapor of desorption enter the firing chamber and fully burnt.When idle running then automatically control stop desorption, promptly close the passage of charcoal jar (3) and carburetor air pipe (6), to guarantee sufficient combustion.
Pressure vacuum valve (2) is made of pressure valve (9), vacuum valve (10), peripheral side dividing plate (11), supporting frame (12), seal washer (13), the breathing pipe (14) that communicates with canister (3) and fuel tank cap shell (15) with holes, when the gasoline vapor pressure in the fuel tank (1) is higher than the atmospheric pressure certain value, pressure valve (9) is opened, and the gasoline vapor in the fuel tank (1) flows into charcoal jar (3) by the road and is adsorbed.When vapor pressure was less than atmospheric pressure in the fuel tank (1), vacuum valve (10) was opened, and ambient air flows in the fuel tank (1) through charcoal jar (3), vacuum lock occurs to prevent oil circuit.Hole on pressure vacuum valve (2) lower partition (11) peripheral side, can stop when fuel tank (1) heavy curtain is moving that gasoline outbound flows in the case spatters, and does not hinder passing through of gasoline vapor again, thereby has played the effect of separation gasoline and gasoline vapor.
This device is tested on NJ134A Beijing goods vehicle motor of making a leapleap forward that Nanjing Automobile factory makes, and effect is fairly obvious: under the typical condition of short distance, temperature is 20 ℃-30 ℃, and with homemade No. 70 gasoline, may command reclaimed and reached 100 gram gasoline every day.An automobile is annual by calculating on 300 day Working day, annual recyclable 30 kilograms of gasoline.Calculate as pressing 2,000,000 automobiles in the whole nation, year 60000 tons of gasoline of loss, and if can all recycle will be an individual surprising fuel-economizing numeral.Beijing has 200,000 automobile runnings every day approximately, the annual loss 6 kiloton gasoline of failing to keep an appointment, and these gasoline vapors distribute in the living space that the crowd is dense, and as being 10 mg/litre to contain HC concentration, contaminated space, Beijing reaches 6 billion cubic meters approximately.This will be seriously the prestige health of assisting the people.
