One, the engine exhausts the exhaust gas, pushes the turbine exhaust end of the turbine impeller (turbine Wheel) and makes it rotate. Thus, the compressor impeller (turbine Wheel) which is connected with the other side can be driven simultaneously.
Second, the compressor impeller to the air from the inlet forced suction, and the rotation of the blades after compression, and then into the pipe diameter more and more large expansion channel outflow, these compressed air is injected into the cylinder combustion.
Third, some engines with intercooler, in order to reduce the compressed air temperature, increase density, to prevent the engine from detonation.
Four, compressed (and cooled) air enters the cylinder through the inlet pipe and participates in the burning work.
Five, the exhaust gas discharged from the exhaust pipe, into the turbine, and then repeat the above (one) action.
