Through the single stage supercharging piston engine’s research

two-stage supercharging applications in this type were applied.The air compressor series and the turbine wheel parallel scheme of arrangement were used to establish the modeling of the engine with GT-Power. According to same-flow method

two-stage supercharger matching was conducted and the waste gate valve flow regulation was calculated.The result demonstrates the turbine wheel and the air compressor in the overall height moves in the high efficiency area

and two levels of supercharging system’s developments have provided the good foundation.
