The invention aims at providing an electromagnetic control booster-type valve system. The electromagnetic control booster-type valve system comprises a hydraulic oil rail, electromagnetic control parts, valve bodies, an oil tank and the like. According to the electromagnetic control booster-type valve system provided by the invention, by adopting the hydraulic oil rail, the valve opening and closing instability caused by pressure fluctuation in the system is remarkably reduced, and the reliability and the consistency of working of the valve system are guaranteed; control valves are controlled to open and close hydraulic oil paths by power on-off of the corresponding electromagnetic control parts; boosting pistons are used to boost hydraulic oil in corresponding boosting cavities, thereby realizing the connection and disconnection between valves and corresponding ventilation ports; and valve timing and a valve duration angle can be effectively controlled, the realization of flexible valve modes of an internal combustion engine under different working conditions is facilitated, the degree of freedom of valve control is remarkably improved, the economy of fuel and the emission of the internal combustion engine can be further improved, and dynamic performance of the internal combustion engine is favorably improved.
