Turbocharged engine hybrid intake structure and intake control method

The invention discloses a turbocharged engine hybrid intake structure and an intake control method, and belongs to the technical field of engines. The hybrid intake structure comprises a superchargedintake pipe, a natural suction intake pipe, an intake manifold and an electric control unit; the supercharged intake pipe communicates with the intake manifold; a first intake pressure sensor is arranged in the intake manifold; and a second intake pressure sensor and an on-off valve are arranged in the natural suction intake pipe. The intake control method adopts the hybrid intake structure. The electric control unit can control the on-off valve to open and close so as to change the intake mode of an engine according to the pressure of the intake manifold detected by the first intake pressuresensor and the pressure of the natural suction intake pipe detected by the second intake pressure sensor. The economy, dynamic property and emission in the middle-low-speed stage of an automobile canbe improved, the sudden fee
