Embodiment
For ease of the understanding of technical solution of the present invention, be introduced below in conjunction with concrete mode of execution.
As shown in Figure 1, vehicle fuel steam adsorption tanks of the present invention are fixed in the machine liquid/gas separator 30 on the fuel vapor absorption tank body and are supported base 11 formations of active carbon built-in in the fuel vapor adsorption tanks body to prevent its outflow by fuel vapor absorption tank body 10.
Automobile fuel oil steam adsorption tanks of the present invention have connected intake channel 31 with junctor liquid/gas separator and fuel tank on the machine liquid/gas separator.On fuel vapor absorption tank body, also be provided with an air suction tracheae 33 simultaneously to suck or exhausting air.
Concrete inside is provided with as shown in Figure 2.
Be connected with a plurality of sucking pipe nozzles 35 on the leading pipe 32 of the round table-like liquid trap 34 of composition machine liquid/gas separator, the inner bottom surface of liquid trap is the plane of inclination 37 that middle body is higher than external lateral portion, and the bottom of liquid trap is connected with disperser 38.
Wherein, the angle of inclination of plane of inclination forms 1-3 °, and preferred 2 °.Leading pipe stretches into the inside of liquid trap, its role is to that fuel vapor is adsorbed the liquid fuel that flows in the gaseous fuel that adsorbs in the tank body and the machine liquid/gas separator and is transferred to motor.The effect of sucking pipe nozzle is to make the liquid fuel that flows in the liquid trap flow into leading pipe, and the length of sucking pipe nozzle is set to 4-7cm, and preferred 5cm, and diameter is set to 2-3mm, and preferred 2.5mm.The number optimum of sucking pipe nozzle is more than 4, therefore, even cause liquid fuel to tend under the situation of a side in the liquid trap run-off the straight, also can evenly suck from the gaseous fuel of all directions with fuel and active carbon adsorption, supplies to motor simultaneously.
The joint of sucking pipe nozzle and leading pipe is to the inboard outstanding formation raised structures of leading pipe, and the aperture of the connection part of sucking pipe nozzle and leading pipe diminishes gradually to form throttle orifice pipe 43, as shown in Figure 4.The length of the end of leading pipe from the throttle orifice pipe to the bottom forms 2-4cm, and preferably forms 3cm.
Front end at the sucking pipe nozzle connects auxiliary mouthful 36 of absorption, makes that the liquid fuel in the machine liquid/gas separator can flow into swimmingly, and absorption forms with certain interval for auxiliary mouthful.
The inflow entrance 40 of disperser is to the outstanding certain-length in its inner space, so that the gaseous fuel that flows into is distributed to the whole space of fuel vapor adsorption tanks equably.Below disperser, open a plurality of through holes 39,, and realize being communicated with of tank body and liquid trap so that gas disperses to multi-direction equably by through hole.
Above-mentioned fuel vapor adsorption tanks body is made as the shape that is suitable for installing in the vehicle, communicates for active carbon built-in in the body is not flowed out with air, is provided with bed course 13 and the taper spring 12 that is used to support active carbon in tank body, and bed course is sponge or felt.Taper spring has not only supported built-in more active carbon, the body oscillating that produces when playing the absorption vehicle operating simultaneously and the effect of shock absorbing.
Bed course is divided by the inner next door that is provided with 14 of fuel vapor adsorption tanks, its be fixed in built-in active carbon 17 first chamber 15 top and below, be fixed in the top of the second chamber 15a and below, and also be fixed with bed course in buffer wall 16 above and below of first chamber and second chamber, this bed course makes active carbon built-in in first chamber and second chamber keep being separated from each other and unmixed state, and prevents that active carbon is broken.
Wherein, first chamber and second chamber are also to be divided by the next door, a large amount of built-in active carbons that are used to adsorb from the boil-off gas of fuel tank inflow in first chamber, the built-in more easily detachable different types of active carbon of active carbon of comparing first chamber in second chamber.
Fig. 5 is the cut-away section stereogram of another embodiment of the present invention, and wherein liquid trap is the elliptical table shape, and the inner sucking pipe nozzle that is provided with, the auxiliary mouth of absorption, plane of inclination, disperser etc., with the front be equivalent arrangements.
In above-mentioned vehicle fuel steam adsorption tanks, liquid fuel that contains in the gaseous fuel that will flow into from fuel tank and the liquid fuel that is produced by temperature reduction or anomaly are stored in the machine liquid/gas separator in addition, and under the machine liquid/gas separator disperser is set, so that the gaseous fuel that flows into is distributed on the active carbon of filling in the fuel vapor adsorption tanks equably and is adsorbed on the active carbon.
And, the ramped bottom surface of liquid trap is with certain angle tilt setting, to compile liquid fuel in the outside, a plurality of sucking pipe nozzles are set on leading pipe, the gaseous fuel of fuel vapor adsorption tanks absorption motor can be transferred under its suction function that in motor, produces, also motor can be transferred in the lump with the liquid fuel in the opportunity liquid/gas separator.
The sucking pipe nozzle is to multi-direction setting, even if make the fuel vapor adsorption tanks be inclined under the situation of a side in the vehicle run-off the straight, and also can be by the sucking pipe nozzle inhalant liquid fluid fuel of multi-direction setting.
Technique scheme has only embodied the optimal technical scheme of technical solution of the present invention, those skilled in the art to some part wherein some changes that may make all embodied principle of the present invention, belong within protection scope of the present invention.
