PROBLEM TO BE SOLVED: To provide a methane fermentation gas automobile system operable without reducing a combustion efficiency of an automobile by stably removing impurities such as siloxane in methane fermentation gas. SOLUTION: This automobile system using as fuel, methane fermentation gas containing at least hydrogen sulfide, carbon dioxide and siloxane as impurities, is provided with a methane fermentation gas refiner 21 having a desulfurizer 23 for removing hydrogen sulfide in methane fermentation gas and a CO<SB>2</SB>removal device 24 arranged on the downstream side of the desulfurizer 23, and an ozone treatment device 26 arranged on the downstream side of the CO<SB>2</SB>removal device and dissolving siloxane in methane fermentation gas.
