The two-stage supercharging system has the characteristics of high supercharging ratio and large flow range, and reasonable matching can ensure that all stages of compressors and turbines operate in a high constant entropy efficiency area, so that the energy utilization of waste gas is more reasonable compared with a single-stage turbocharging system. By skillfully utilizing the bypass valves at the vortex end and the pressure end of each stage, the air intake requirement of any complex combustion scheme can be almost met.
