The invention provides a parallel
system of a twin-turbo
supercharger, relating to the technical fired of
combustion motors, and comprising air compressors, an air inlet
pipe, an engine, an air
exhaust pipe, turbos, a volume chamber, connection pipes, a
moving body, a spring and penetration pipes, wherein the
moving body is installed in the volume chamber and further contacts with the inner wall face of the volume chamber in a sealing way; the first penetration
pipe and the second penetration
pipe penetrate through the
left wall face and the right wall face of the
moving body; and the lower wall face of the moving body is connected with the lower wall face of the volume chamber through the spring. When the engine is located under the
low speed working condition, the moving body moves downward; only the first
air compressor and the first turbo work; the
pulse energy is fully utilized; the air
inlet pressure of the engine is higher; and the overall performance of the engine is better. When the engine is located in the high speed working condition, the moving body moves upward; the first
air compressor, the second
air compressor, the first turbo and the second turbo simultaneously work; the pumping loss of the engine is less; and the overall performance of the engine is better. The parallel
system of the twin-turbo
supercharger is rational in design, simple in structure and applicable for a turbo charging
system with two turbo superchargers.
