A hydraulic mount of an automobile engine comprises a rubber main spring, a shell, an upper liquid chamber, a decoupling film, a middle liquid chamber and a lower liquid chamber. The outer surface ofthe rubber main spring is connected with the inner surface of the shell in an attached mode, an upward-concave chamber is formed in the lower end of the rubber main ring, a liquid adding channel is formed in the upper end of the rubber main ring, and a steel ball is arranged in the liquid adding channel. The upper liquid chamber is in an inverted bowl shape, an inverted small bowl is arranged in the middle of the top of the upper liquid chamber, a plurality of middle liquid passing holes are formed in the bottom of the inverted small bowl, and a side liquid passing hole is formed in the edge of the top of the upper liquid chamber. A space is defined by the side wall, the chamber top and the chamber bottom of the middle liquid chamber, the lower end of the upper side wall of the middle liquid chamber is fixedly connected with the chamber top of the middle liquid chamber, the chamber top of the middle liquid chamber is provided with an outer concave part and an inner concave part, an upper throttling hole is formed in the inner concave part, and a lower throttling hole is formed in the chamber bottom of the middle liquid chamber. The decoupling film is arranged in a space defined bythe top of upper liquid chamber, the upper side wall of the middle liquid chamber and the top of the middle liquid chamber. The corresponding side faces of the upper liquid chamber side wall, the lower liquid chamber side wall and the chamber define a side liquid storage chamber. A middle damping liquid flow channel is defined by the corresponding surfaces of the upper liquid chamber and the rubber main spring.
