Description
Technical field
The utility model is related to a kind of fuel tank of vehicle more particularly to a kind of fuel tank pipeline structures.
Background technology
During automobile fuel filler, fuel tank and fuel filler cap must there are one reliable piping connections, in order to keep away
Exempt from the fluid for shaking out from fuel tank and enter such pipeline, pipeline is needed to be come out from fuel tank along fuel tank upper shell always at present
Arrangement upwards, must not have liquid.
However, due to the limitation of vehicle body condition, generally require, across vehicle body or crossbeam, to bring pole when arrangement upwards
Big Change cost.
Utility model content
The purpose of this utility model is to be directed to above-mentioned present situation, is provided a kind of without pass through vehicle body or the fuel tank of crossbeam
Pipeline structure.
The technical solution adopted in the utility model：A kind of fuel tank pipeline structure, including fuel tank, setting are in the fuel oil
The activated carbon canister of case side, the oil filling pipe being connected to the fuel tank, the connection fuel tank and activated carbon canister first pipe,
And the second pipe of the connection first pipe and oil filling pipe, the fuel tank is hollow babinet, internal that fuel oil is housed,
The upper surface middle part of the fuel tank be equipped with a blow vent, the activated carbon canister mounted in automobile the fuel tank and engine it
Between, and the level height of the upper surface of the level height fuel tank of the activated carbon canister is low, the oil filling pipe is set to institute
State one end of fuel tank and be connected in the fuel tank, the first pipe is arranged in the upper surface of the fuel tank, and compared with
The level height of the activated carbon canister is high, and the first pipe is equipped with threeway, the second pipe at the activated carbon canister
One end be connected in the threeway, the other end is connected on the oil filling pipe.
The effect of the utility model is：The fuel tank pipeline structure avoids the connection fuel tank and the pipeline of oil filling pipe is deposited
In the possibility of hydrops, while also more freedom and flexibility are moved towards, avoids change body structure.
Description of the drawings
Fig. 1 is a kind of vertical view of fuel tank pipeline structure provided by the utility model；
Fig. 2 is the side view of fuel tank pipeline structure shown in FIG. 1.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
It is a kind of fuel tank pipeline structure provided by the utility model comprising fuel tank please refer to Fig. 1 and Fig. 2
1, it is arranged in the activated carbon canister 2 of 1 side of fuel tank, the oil filling pipe 3 being connected to fuel tank 1, connection fuel tank 1 and activated carbon canister 2
First pipe 4 and be connected to first pipe 4 and oil filling pipe 3 second pipe 5.
Fuel tank 1 is hollow babinet, internal that fuel oil is housed.The upper surface middle part of fuel tank 1 is equipped with a blow vent, and
The upper surface of fuel tank 1 is recessed inwardly to form a container around the blow vent, which extends from the side of fuel tank 1
To the other side.
Activated carbon canister 2 is between the fuel tank 1 and engine of automobile, and the level height of activated carbon canister 2 is compared with fuel tank 1
Upper surface level height it is low.Activated carbon canister 2 escapes into air for fuel-steam after avoiding engine stop from operating.When starting
After machine is flame-out, fuel-steam in in-tank mixing and is stored in activated carbon canister 2 with fresh air, after engine start, is mounted in
Electromagnetic valve between activated carbon canister 2 and air inlet pipe is opened, and the fuel-steam in activated carbon canister 2 is acted in the vacuum degree of air inlet pipe
Lower brought by pure air participates in burning in cylinder.Discharge is not only so reduced, and also reduces oil consumption.
Oil filling pipe 3 be set to one end of fuel tank 1 and be connected in fuel tank 1, when for refueling and external connection.
First pipe 4 is arranged in the upper surface of fuel tank 1, and compared with the level height of activated carbon canister 2 height.First pipe 4 is certainly
The blow vent of fuel tank 1 extends to the side of fuel tank 1, re-extends receiving in the container of fuel tank 1, finally and activated carbon
Tank 2 connects.First pipe 4 is equipped with threeway 41 at close activated carbon canister 2.
Second pipe 5 is connected to first pipe 4 and oil filling pipe 3, and one end of second pipe 5 is connected in threeway 41, another
End is connected on oil filling pipe 3.
The first pipe 4 and second pipe 5 are when arrangement, first arrangement downwards, in minimum point (at activated carbon canister) or
The position of person close to minimum point connects the threeway, then pipeline is up arranged, so avoids and connects the fuel tank 1 and second
The pipeline of pipeline 5 keeps the fuel tank that can be connected to all the time with oil filling pipe there are the possibility of hydrops, while moving towards also more
Freedom and flexibility avoid change body structure.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
