Description
Technical field
The technical field that the fuel evaporation that the utility model relates to supercharged engine reclaims.
Background technique
Gasoline is volatile fuel, fuel oil in fuel tank can volatilize very soon increases the pressure of fuel tank internal, certain danger will be produced when pressure arrives certain value, angle for fuel saving and protection of the environment is set out, petrol engine increases EVAP Evaporative System, namely the canister arranged, the inner active carbon very strong by adsorptivity of canister is filled, fuel vapor unnecessary in fuel tank is no longer discharged in air, when start time, canister control valve is opened in good time, again the fuel vapor of absorption is poured into intake manifold by negative pressure, to reach the object of saving fuel oil and environmental protection.But intake manifold is malleation in supercharged engine major part working environment, traditional fuel vapor to be sucked intake manifold by negative pressure infeasible, therefore needs to improve EVAP Evaporative System device.Structural volume can't affect the fixing of air condition compressor and adjustment simultaneously; And for preventing supercharged engine from reaching malleation when pressurized machine works in intake manifold thus causing oil gas in oil gas desorption pipe to flow backwards, pressurised oil gas desorption pipe need be redesigned.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel oil gas desorption pipe, the utility model is in order to when to overcome existing supercharged engine inlet manifold be malleation, can not affect the problem of the fixing of air condition compressor and adjustment in the improvement situation that oil gas desorption pipe can not stop oil gas to flow backwards.A kind of Novel oil gas desorption pipe of the present utility model, it is made up of the first oil gas desorption pipe, the second oil gas desorption pipe, the 3rd oil gas desorption pipe, the 4th oil gas desorption pipe, the 5th oil gas desorption pipe, threeway, the first one-way valve, the second one-way valve;
One end of first oil gas desorption pipe is communicated with a port of threeway, another two ports of threeway are communicated with a port of the 3rd oil gas desorption pipe with a port of the second oil gas desorption pipe respectively, another port of second oil gas desorption pipe is communicated with the air inlet port of the first one-way valve, the air outlet of the first one-way valve is communicated with a port of the 4th oil gas desorption pipe, another port of 3rd oil gas desorption pipe is communicated with the air inlet port of the second one-way valve, the air outlet of the second one-way valve is communicated with a port of the 5th oil gas desorption pipe, first oil gas desorption pipe, second oil gas desorption pipe, 3rd oil gas desorption pipe, 4th oil gas desorption pipe, 5th oil gas desorption pipe, threeway, first one-way valve and the second one-way valve all use clip to be connected, when pressurized machine does not work, first oil gas desorption pipe pressure=the second oil gas desorption pipe > the 4th oil gas desorption pipe pressure, so now the first closed check valve, second one-way valve is opened, and oil gas enters intake manifold from the first oil gas desorption pipe, the 3rd oil gas desorption pipe, the second one-way valve, the 5th oil gas desorption pipe, when pressurized machine works, first oil gas desorption pipe pressure < the 3rd oil gas desorption pipe pressure < the 5th oil gas desorption pipe pressure, so now the first one-way valve is opened, second closed check valve, oil gas enters pressurized machine flow to intake manifold from the first oil gas desorption pipe, the second oil gas desorption pipe, the first one-way valve, the 4th oil gas desorption pipe.
The utility model can be fixed when realizing air condition compressor and adjust, effective reduce take up space and the amount of parts of required management and assembling, and the problem that can prevent oil gas from flowing backwards.Also have the life-span long, easily manufacture, advantage that reliability is high.
