Engine gasoline steam absorption and reutilization device

The invention discloses an engine gasoline steam absorption and reutilization device which comprises a gasoline tank gasoline steam breather pipe, an arc-shaped carbon tank and a negative pressure pipe. An arc-shaped gas distribution pipe is arranged in the arc-shaped carbon tank in the arc direction of the arc-shaped carbon tank, an arc-shaped activated carbon chamber is formed between the arc-shaped gas distribution pipe and the arc-shaped carbon tank, and an arc-shaped sliding channel is formed in the arc-shaped gas distribution pipe. The gas distribution unit can actively rotate and move along an arc path of the arc sliding channel, the gas outlet end of the negative pressure pipe is communicated with a gas inlet manifold of the engine, and the gas extraction end of the negative pressure pipe is communicated with the arc activated carbon chamber through the gas distribution unit, so that the negative pressure desorption efficiency can be improved; the two actions of the conical hole plugging head can auto
