[0010] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0011] like Figure 1As shown, the utility model provides an oil and gas desorption system suitable for various boundaries, including a venturi valve 1, a venturi tube 2, a three-way valve 5, a carbon canister control valve end pipeline 6, a carbon canister control valve 7 and a double-ended quick plug 10; the carbon canister control valve 7 is connected to the vehicle fuel tank, the carbon canister control valve 7 is fixed on the engine through a plug, the carbon canister control valve 7 is connected to the inlet of the three-way valve 5 through the carbon canister control valve end pipeline 6, the outlet 1 of the three-way valve 5 is connected to the intake manifold through the double-ended quick plug 10, the outlet 2 of the three-way valve 5 is connected to the front of the supercharger through the venturi valve 1, the venturi tube 2 is connected to the front of the supercharger and the intake manifold through the double-ended quick plug 10 and the venturi valve 1, the three-way valve 5 is fixed on the engine, the venturi valve 1 is installed in front of the supercharger, and the double-ended quick plug 10 is installed at the intake manifold.

[0012] An outlet of the three-way valve 5 is connected to a double-ended quick connector 10 via a low-pressure desorption pipeline 8 .

[0013] The second outlet of the three-way valve 5 is connected to the Venturi valve 1 through the high-pressure desorption pipeline 3 .

[0014] The three-way valve 5 is a three-way valve integrating a pressure sensor and a two-way one-way valve.

[0015] A one-way valve is integrated on the pipe opening connecting the Venturi valve 1 and the Venturi tube 2, so that the gas in the intake manifold cannot enter in the reverse direction.

[0016] The venturi tube 2 and the low-pressure desorption pipeline 8 are both covered with a sheath 9 .

[0017] A cable tie 4 is installed on the high-pressure desorption pipeline 3 .

[0018] Working principle: when the supercharger is not working, the intake manifold is at negative pressure, and the oil and gas enter the intake manifold through the low-pressure desorption pipeline 8 to participate in combustion; when the supercharger is working, the intake manifold is at positive pressure, and the one-way valve at the outlet of the three-way valve 5 connected to the low-pressure desorption pipeline 8 is cut off, and the oil and gas finally enter the intake manifold before the intake supercharger through the high-pressure desorption pipeline 3 to participate in combustion. The addition of the Venturi tube 2 increases the desorption flow at the high-pressure end through the Venturi effect, and the Venturi valve 1 adds a one-way valve to prevent the intake manifold gas from flowing back.
