The invention discloses a recycling system for automobile fuel volatiles. The recycling system comprises a closed gasoline tank and a fuel steam recoverer on the automobile; the gasoline tank furthercomprises a fuel steam delivery pipe, the fuel steam overflowing end at the top of the gasoline tank communicates with the air inlet end of the fuel steam delivery pipe, and the air outlet end at thetop of the fuel steam delivery pipe communicates with the gas inlet end of the fuel steam delivery pipe, and the gas outlet end of the fuel steam delivery pipe communicates with the fuel steam air inlet end of the fuel steam recoverer. With a simple structure, the recycling system can store fuel steam of a fuel tank continuously, and alleviate the pressure of the fuel tank; when the pressure is increased to a critical value of pressure relief, the pressure of the fuel tank can be released in time, the released fuel steam can be recovered and absorbed in time, and the adsorbed gasoline can be re-evaporated by negative pressure for combustion of an engine.
