The invention provides a liquid fuel oil recovery system and a vehicle with the same, the liquid fuel oil recovery system is characterized in that an oil tank is internally provided with an oil filling limiting valve and a gravity valve, the gravity valve is provided with a first exhaust port, and the gravity valve is communicated with an oil storage space of the oil tank; the first-stage oil-gas separator is located in the oil tank, a first gas inlet of the first-stage oil-gas separator is communicated with the refueling limiting valve, the first-stage oil-gas separator is provided with a second gas outlet, the second-stage oil-gas separator is located in the oil tank and provided with a second gas inlet, a third gas inlet and a third gas outlet, and the second gas inlet is communicated with the second gas outlet. The third air inlet is communicated with the first exhaust port, the third exhaust port is communicated with the activated carbon canister, and the second exhaust port and the second air inlet are arranged in a height difference mode in the height direction of the oil tank. The oil-gas separators are arranged in the oil tank, fuel oil leakage is avoided, after liquid fuel oil in the first-stage oil-gas separator enters the second-stage oil-gas separator, secondary oil-gas separation is conducted, and the liquid fuel oil is prevented from entering the activated carbon canister.
本发明提供了一种液态燃油回收系统及具有其的车辆,包括:油箱内设置有加油限量阀和重力阀,重力阀设有第一排气口,重力阀与油箱的储油空间连通设置;一级油气分离器位于油箱内,一级油气分离器的第一进气口与加油限量阀连通设置,一级油气分离器设有第二排气口二级油气分离器位于油箱内,二级油气分离器设有第二进气口、第三进气口和第三排气口,第二进气口与第二排气口连通,第三进气口与第一排气口连通,第三排气口与活性炭罐连通,第二排气口与第二进气口在油箱的高度方向存在高度差地设置。油气分离器均设置油箱内,避免燃油外泄,一级油气分离器内的液态燃油进入二级油气分离器后,进行二次油气分离,避免液态燃油进入活性炭罐。
