Abstract
The utility model relates to a kind of hot type charcoal canister, and the top of canister is provided with adsorption port, desorption mouth and air inlet, side top and is provided with engine cooling water out, side-lower and is provided with engine cooling water inlet, is located at solenoid valve on engine cooling water inlet and the mobile water cavity of Cooling Water of canister inwall surrounding; Solenoid valve is controlled by engine management computer.Adopt after technique scheme, can not increase again the oil consumption of motor to the heating of charcoal tank, can not reduce intake efficiency simultaneously.
Description
Technical field
The utility model relates to a kind of auto parts machinery, is specifically related to a kind of automobile canister of controlling motor vehicle gasoline evaporation.
Background technique
The canister that fuel evaporation is controlled in releasing system comprises canister body, is arranged on the adsorption port on canister body, desorption mouth and air inlet, and be filled in the intrinsic active carbon of canister.Wherein, adsorption port is connected with fuel tank pipeline, and the fuel-steam in engine stoping operation rear fuel tank, has been avoided fuel vapor to escape into atmosphere and caused atmospheric pollution by the active carbon adsorption in canister by fuel tank pipeline.The desorption mouth of canister is connected with engine air inlet tube by solenoid valve, and after engine start, electrical control system for engine is controlled solenoid valve and opened, and canister and engine air inlet tube are communicated with.The scavenging air that the pressure official post that the air inlet place of engine air throttle body and canister exists enters from air inlet is through active carbon flow direction engine throttle body, mobile scavenging air can make fuel vapor molecule break away from the absorption of active carbon, and enters motor participation burning with air.Like this, by canister, can avoid fuel-steam to escape into atmosphere and cause atmospheric pollution.Simultaneously can also fuel saving.
Chinese patent literature (CN202510252 and CN202325912) disclose adopt Electric heating charcoal tank, the desorption ability of gasoline vapour while having improved desorption, yet adopt Electric heating to increase on the one hand the burden of generator or storage battery, increase the oil consumption of motor simultaneously, if the excess Temperature of heating can make again the air that enters motor via charcoal tank be heated rear excess Temperature on the other hand, density is diminished, reduced the intake efficiency of motor.
Model utility content
The technical problems to be solved in the utility model is: a kind of hot type charcoal canister is provided, adopts engine coolant to come the heating of charcoal tank, can not increase again the oil consumption of motor to the heating of charcoal tank, maintain original intake efficiency.
The technological scheme that realizes above-mentioned purpose is: a kind of active carbon pot for vehicle, and the top of described automobile-used activated carbon canister is provided with adsorption port, desorption mouth and air inlet, side top and is provided with engine cooling water out, side-lower and is provided with engine cooling water inlet, is located at solenoid valve on engine cooling water inlet and the mobile water cavity of Cooling Water of canister inwall surrounding; Solenoid valve is controlled by engine management computer; Automobile-used activated carbon canister internal cavities is provided with the active carbon of adsorbed gasoline, described adsorption port is connected with petrol tank, and desorption mouth is connected with engine air inlet tube by solenoid valve, and air inlet communicates with ambient atmosphere, and the water-cooling tube of motor is provided with cooling-water temperature sensor; Described engine cooling water inlet, engine cooling water out and cooling water pipe of engine are connected in parallel.
Adopt after technique scheme, there is following beneficial effect:
This hot type charcoal canister, adopts engine coolant to come the heating of charcoal tank, during engine work, because water temperature stability is in 90 degree left and right, can not increase again the oil consumption of motor to the heating of charcoal tank, can not reduce intake efficiency simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is principle schematic of the present utility model.
In figure: 1. engine cooling water out; 2. adsorption port; 3. desorption mouth; 4. air inlet; 5. active carbon; 6. water cavity; 7. engine cooling water inlet; 8. solenoid valve; 9. wire; 10. cooling-water temperature sensor.
Embodiment
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1: a kind of active carbon pot for vehicle, the top of described automobile-used activated carbon canister is provided with adsorption port 2, desorption mouth 3 and air inlet 4, side top and is provided with engine cooling water out 1, side-lower and is provided with cooling water inlet 7, is located at solenoid valve 8 on engine cooling water inlet 7 and the mobile water cavity 6 of Cooling Water of canister inwall surrounding; Solenoid valve 8 is controlled by engine management computer; Active carbon 5, described adsorption port 2 that automobile-used activated carbon canister internal cavities is provided with adsorbed gasoline are connected with petrol tank, desorption mouth 3 is connected with engine air inlet tube by solenoid valve 8, air inlet 4 communicates with ambient atmosphere, and the water-cooling tube of motor is provided with cooling-water temperature sensor 10; Described engine cooling water inlet 7, engine cooling water out 1 are connected in parallel with cooling water pipe of engine.
Working principle of the present utility model is as follows: after engine operation and engine water temperature reach 90 while spending, engine management computer-controlled electromagnetic valve 8 is opened, the engine cooling water water cavity 6 of flowing through, to active carbon 5 heating in charcoal canister, thereby the gasoline vapour acceleration desorption from active carbon 5 that enters active carbon 5 and adsorbed by active carbon 5 from adsorption port 2 before making it, then accompany the fresh air that air inlet 4 enters and go out and enter engine air inlet tube from desorption mouth 3, finally enter that cylinder is burned to be fallen.When motor is not worked, engine management computer-controlled electromagnetic valve 8 cuts out, and the gasoline vapour in petrol tank can enter in charcoal tank by adsorption port 2, and is adsorbed by active carbon 5, thereby makes the pressure drop in petrol tank; When firm ato unit, because water temperature does not arrive value 90 degree working properly, in order to make engine water temperature reach as early as possible normal value, make motor reach optimal operational condition, this solenoid valve 8 is not opened, prevent that heating makes water temperature rising slowly affect engine work, particularly winter on charcoal tank due to engine cooling water.
What in above specification, describe is embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field read after specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of model utility.
