Description
Technical field
The utility model relates to engine art, particularly relates to a kind of desorption pipeline.
Background technique
The function of canister is, the steam that in absorption fuel tank, fuel oil produces.Prevent from causing environmental pollution in HC diffusion of vapor to air.The vacuum that canister relies on motor to produce carries out desorption to it, and the HC desorption of internal reservoir is delivered to motor and burnt.
The vacuum that after traditional naturally aspirated engine utilizes engine running, below the throtlle valve produces carries out desorption to canister.Easily cause engine motor oil and other gas backflows to cause canister to lose efficacy, and cause the problem of turbosupercharged engine canister desorption deficiency.
Model utility content
In order to solve the problems of the technologies described above, the utility model discloses a kind of desorption pipeline, solve engine motor oil and other gas backflows cause canister to lose efficacy, and cause the problem of turbosupercharged engine canister desorption deficiency.
According to an aspect of the present utility model, provide a kind of desorption pipeline, comprising:
Three way type one-way valve, suction tude, the first connecting tube and the second connecting tube;
The first end of described Three way type one-way valve is connected with the first end of described suction tude, and the second end of described suction tude is connected with solenoid valve air outlet;
Second end of described Three way type one-way valve is connected with the first end of described first connecting tube, and the second end of described first connecting tube is connected with pressurized machine suction port end;
3rd end of described Three way type one-way valve is connected with the first end of described second connecting tube, and the second end of described second connecting tube is connected with intake manifold.
Alternatively, the material of described first connecting tube is nylon.
Alternatively, the material of described second connecting tube is nylon.
Alternatively, the material of described first connecting tube is rubber.
Alternatively, the material of described second connecting tube is rubber.
The beneficial effects of the utility model are:
Pipeline of the present utility model adopts integrated form to connect, and prevents engine motor oil and other gas backflows to cause canister to lose efficacy, and solves the not enough problem of turbosupercharged engine canister desorption, makes supercharging vehicle what operating mode in office have desorption vacuum source.Solve the fuel-steam desorption problem of supercharged engine vehicle easily, effectively ensure that car load discharge vaporization.
Accompanying drawing explanation
Fig. 1 is the explosive view of desorption pipeline described in the utility model embodiment.
Description of reference numerals:
1, Three way type one-way valve; 2, suction tude; 3, the first connecting tube; 4, the second connecting tube.
Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, in embodiment of the present utility model, provide a kind of desorption pipeline, comprising:
Three way type one-way valve 1, suction tude 2, first connecting tube 3 and the second connecting tube 4;
The first end of described Three way type one-way valve 1 is connected with the first end of described suction tude 2, and the second end of described suction tude 2 is connected with solenoid valve air outlet;
Second end of described Three way type one-way valve 1 is connected with the first end of described first connecting tube 3, and the second end of described first connecting tube 3 is connected with pressurized machine suction port end;
3rd end of described Three way type one-way valve 1 is connected with the first end of described second connecting tube 4, and the second end of described second connecting tube 4 is connected with intake manifold.
This pipeline adopts integrated form to connect, perfectly by engine electromagnetic valve and engine intake manifold and turbocharger of motor inlet end, couple together, and prevent engine motor oil and other gas backflows from causing canister to lose efficacy, and solve the not enough problem of turbosupercharged engine canister desorption, make supercharging vehicle what operating mode in office have desorption vacuum source.This kind of structural design is simple, solves the fuel-steam desorption problem of supercharged engine vehicle easily, effectively ensure that car load discharge vaporization.
Alternatively, in order to the sealing of the convenience of installing and connection, usually the material of each connecting tube is selected according to the structure and material of described Three way type one-way valve interface.
Generally, it is convex table type and bamboo joint type two kinds that described Three way type one-way valve comprises interface, accordingly, different according to the interface structure material of described Three way type one-way valve, and the material of each connecting tube is chosen to be nylon or rubber.It should be noted that, the Material selec-tion of described Three way type one-way valve and each connecting tube is not limited only to above-described material.
Above-described embodiment of the present utility model, according to different needs, can select the material of described Three way type one-way valve and each connecting tube.More can adapt to the needs of different motor.The Placement that the utility model desorption pipeline is integrated, greatly reduces number of components, reduces cost, decrease packing, thus reduces the working pressure of installation personnel.
And the technical solution of the utility model can realize supercharging vehicle fuel-steam the effect of desorption vacuum source at any time.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
