Description
Technical field
The invention belongs to motor vehicle emission control technique field, specifically, relate to the fuel-steam processing system on the bestride type vehicle.
Background technique
Because ventilation and hot soak loss between daytime; used in fuel oil system of motor-driven vehicle can produce fuel evaporation pollutant; fuel evaporation pollutant is a carbon compound; can not directly be discharged in the atmosphere; be protection environment, energy saving, China formulates the NBS that bestride type vehicle fuel evaporation pollutant emission limit is arranged.
Existing bestride type vehicle is to install the charcoal jar additional to come fuel evaporation pollutant is adsorbed in oil-fired system, the charcoal jar is connected between fuel tank and the Carburetor, the fuel evaporation pollutant of discharging from fuel tank enters the absorption of charcoal jar, enter Carburetor and air mixing then, form mixed gas and enter Carburetor, enter engine combustion by suction tude again.The fuel-steam mixer is thinner behind the desorption, after participation mixes through Carburetor, the mixture strength that can cause entering the motor internal combustion is lower, such mixed gas participates in burning, may make the engine idle instability, thereby cause the engine operation instability, influence the car load idle stability of bestride type vehicle.And, fuel evaporation desorption mouth is arranged on the Carburetor, can cause the increase of Carburetor technology and cost thereof, be unfavorable for reducing the cost of production of car load.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can reduce fuel-steam can reduce the cost of production of bestride type vehicle again to the influence of discharge vaporization and operating mode Straddle-type vehicle fuel-steam treatment device.
For achieving the above object, bestride type vehicle fuel-steam treatment device provided by the invention, include charcoal jar and gasoline cut-off valve, the steam adsorption port of charcoal jar links to each other with oil tank breather by first pipeline, the gasoline cut-off valve is installed on first pipeline, the pressure controlled valve of charcoal jar links to each other with engine air inlet tube by second pipeline, and the steam desorption mouth of charcoal jar is connected with air-strainer by the 3rd pipeline.
The present invention will be connected with air-strainer with the 3rd pipeline that the steam desorption mouth of charcoal jar is connected, can satisfy the desorption pressure requirement of steam in the charcoal jar, guarantee that steam obtains abundant desorption in the charcoal jar, reduce discharge vaporization, can reduce processing technology again, reduce production costs, and can guarantee, reduce influence the operating mode discharging from the fuel-steam quality of charcoal jar desorption.
Above-mentioned the 3rd pipeline and the tie point of air-strainer are positioned on the trachea of the air-strainer that Carburetor is connected with air-strainer, the negative pressure that makes full use of the generation of this section air flue improves the desorption pressure of steam in the charcoal jar, and owing to the desorption point is arranged on herein, be convenient to regulate the internal diameter in desorption hole, and to almost not influence of cost, and can reach the purpose of desorption.
Further, on the trachea joint that the close air-strainer of the tie point that above-mentioned the 3rd pipeline is connected with air-strainer links to each other with Carburetor, the purpose of She Zhiing is a peak on the air-strainer in this position negative pressure like this, it also is a point of easy desorption combustion gas evaporation, if adjustment vacuum magnitude, the position of desorption point can be moved backward, perhaps changes the internal diameter in desorption hole, the convenient desorption pressure of adjusting desorption point; Thereby guarantee the fuel-steam quality of charcoal jar desorption, reduce the influence of fuel-steam the operating mode discharging.
After adopting technical solution of the present invention, not only reduced the discharging of fuel-steam, and reduced the influence of fuel-steam, also be convenient to adjust the position of desorption point, thereby make the exhaust emissions of bestride type vehicle reach environmental protection requirement more the operating mode discharging.
Description of drawings
Fig. 1 is the overall pie graph of control system of the present invention;
Among the figure: 1. fuel tank; 2. oil tank breather; 3. gasoline cut-off valve; 4. first pipeline; 5. the desorption mouth of giving vent to anger; 6. pressure controlled valve; 7. air inlet adsorption port; 8. second pipeline; 9. the 3rd pipeline; 10. air-strainer; 11. desorption pipe; 12. engine air inlet tube; 13. motor; 14.

Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, it is the charcoal jar of 200ml that charcoal jar 15 adopts storage volumes, guarantees that it has sufficient adsorptive power, and normal sorption fuel-steam quality is about 20 grams.The air inlet adsorption port 7 of charcoal jar 15 links to each other with oil tank breather 2 by first pipeline 4, gasoline cut-off valve 3 is installed on first pipeline 4, the pressure controlled valve 6 of charcoal jar 15 links to each other with engine air inlet tube 12 by second pipeline 8, and the desorption mouth 5 of giving vent to anger of charcoal jar 15 is connected with air-strainer 10 by the 3rd pipeline 9.The 3rd pipeline 9 is positioned on the steam outlet pipe of Carburetor 14 and air-strainer with the tie point of air-strainer 10.First pipeline 4 is also referred to as adsorption tube, and second pipeline 8 is also referred to as the negative pressure pipe, and the 3rd pipeline 9 is also referred to as desorption pipe.
The 3rd pipeline 9 is connected with air-strainer, can satisfy the negative pressure of 9 li of the 3rd pipelines, can satisfy the desorption pressure requirement of steam in the charcoal jar 15 again, guarantee that steam obtains abundant desorption in the charcoal jar 15, reduce discharge of steam, simultaneously, can be according to different requirements, adjust the diameter in desorption hole, and improve fuel-steam quality, reduce influence the operating mode discharging from charcoal jar 15 desorptions.
As can be seen from Figure 1: the 3rd pipeline 9 is communicated with by the desorption pipe on the air-strainer 16 and air-strainer, desorption pipe 11 is installed on the air-strainer trachea joint, owing to be installed in this place, both made things convenient for the installation of desorption pipe 11, also be convenient to the internal diameter size of desorption pipe is adjusted, in addition desorption pipe 11 is arranged on the less end of steam outlet pipe diameter that Carburetor 14 links to each other with air-strainer 10, because this place contacts recently with Carburetor 14, therefore negative pressure herein is the highest, can be when wanting desorption pressure to turn down according to the desorption needs, only desorption pipe 11 need have been moved just backward, so that satisfy the desorption pressure requirement of steam in the charcoal jar 15; Control better from the fuel-steam quality of charcoal jar 15 desorptions, thereby reduce the influence of fuel-steam the operating mode discharging.
Referring to Fig. 1, the fuel-steam of evaporation enters first pipeline 4 by oil tank breather 2 in the closed tank 1, enters the charcoal jar 15 from air inlet adsorption port 7 through gasoline cut-off valve 3 backs to store; When motor 13 operations, produce negative pressure is opened charcoal jar 15 by second pipeline 8 pressure controlled valve 6 in the engine air inlet tube 12, be stored in give vent to anger desorption mouth 5 and three pipeline 9 of fuel-steam by charcoal jar 15 in the charcoal jar 15 and enter near Carburetor 14 and air-strainer 10 interfaces steam outlet pipe, with enter Carburetor after the air mixing of coming from empty filter 10, the mixed gas that comes out from Carburetor enters motor 13 participation burnings, because fuel-steam is participating in having obtained sufficient desorption before the burning, therefore, fuel-steam can not exert an influence to the operating mode of motor.
