Abstract
A compressor and turbine homo-mechanism regulating mechanism in the technical field of internal combustion engines comprises a compressor, a turbine, an engine, connecting pipes, a containing cavity, a moving part, penetrating pipes and an elastic part. Both the first penetrating pipe and the second penetrating pipe penetrate an upper wall and a lower wall of the moving part. A left wall of the moving part is connected with a left wall of the containing cavity through the elastic part. During operation of the engine, the moving part can move left and right in the containing cavity. At low operating speed, left pressure of the moving part is low, the moving part moves to the left, the first connecting pipe and the third connecting pipe are communicated with each other, air intake of the compressor increases relatively, and the compressor barely surges. At high operating speed, left pressure of the moving part is high, the moving part moves to the right, the fifth connecting pipe and the sixth connecting pipe are communicated with each other, air intake of the engine decreases relatively, and detonation pressure of cylinders lowers. The compressor and turbine homo-mechanism regulating mechanism is reasonable in design, simple in structure and applicable to turbocharging systems of engines.
