The invention discloses an air spring type semi-active engine mount which comprises a rubber main spring assembly, an inertia channel body, a rubber bottom membrane, a bottom case, a solenoid valve and a decoupling membrane, wherein the rubber main spring assembly, the inertia channel body, the rubber bottom membrane and the bottom case are assembled into a whole from the top down sequentially; the decoupling membrane is circular and is arranged above the middle of the inertia channel body; an air cavity is formed between the decoupling membrane and the inertia channel body; the air cavity is connected with the atmosphere by a small hole formed in the inertia channel body; the solenoid valve is connected with an electronic control unit of an engine; the opening and closing of the small hole are controlled by the solenoid valve; an upper liquid chamber is formed among the inertia channel body, the decoupling membrane and the rubber main spring; a lower liquid chamber is formed between the inertia channel body and the rubber bottom membrane; an inertia channel surrounding the air cavity is formed in the inertia channel body; and liquid in the upper liquid chamber and liquid in the lower liquid chamber flow via the inertia channel. The air spring type semi-active engine mount is wide in rigidity damping adjustable range, high in response speed, simple in structure, and low in manufacturing cost.
