The invention discloses an automobile fuel tank combined control valve in the field of automobile accessories, which comprises a flange, the flange comprises a containing cavity, an oil-gas separator is arranged in the containing cavity, the oil-gas separator comprises a separation plate, a bottom plate and a circular boss and divides the containing cavity into an exhaust cavity and a liquid accumulation cavity, and a valve body shell is correspondingly arranged below the bottom plate. The valve body shell and the oil-gas separator are clamped to form a combined control valve cavity, the combined control valve cavity comprises a liquid level control valve cavity and a rollover valve cavity, a liquid level control valve element and a rollover valve element are arranged in the liquid level control valve cavity and the rollover valve cavity respectively, and a liquid level control valve exhaust hole corresponding to the liquid level control valve element is formed in the bottom plate. A liquid accumulation cavity exhaust hole is formed in the isolation plate, a rollover valve exhaust hole corresponding to the rollover valve element is formed in the circular boss, and the exhaust cavity is at least communicated with one exhaust pipeline. Oil steam and oil in the oil tank can be separated, fuel oil is prevented from dynamically leaking into a carbon tank in the automobile running process, and oil tank emission is reduced.
