Machine 3,3 compressed air of compressor, increases admission pressure and density, compressed gas enter heat exchanger 9 and cool down, reduces into temperature
Degree further increases density of the induced air, improves the dynamic property of internal combustion engine 1.It is discharged to later using post processing by the exhaust gas of turbine 2
In air.But the exhaust gas in this scenario, discharged after turbine 2 also has higher temperature, some energy can not recycle,
To internal combustion engine waste gas energy underutilization.
2. scheme two：For the exhaust energy that turbine is discharged in further Utilization plan one, the technical solution of the prior art
It is to increase a turbo charge system after turbine 2 on the basis of scheme one, using two turbocharging technology, the two-stage whirlpool
Wheel is used to plenum, but this scheme is not suitable for the little situation of power of IC engine demand, and two-step supercharging system
It is matched with internal combustion engine more complicated.Meanwhile the exhaust gas after two stage turboexpansion still has certain recoverable
Energy, this portion of energy are not recycled.
3. scheme three：When single-stage turbocharging can meet power of IC engine demand, to avoid system matches complicated,
Two turbocharging technology will not generally be used.But on the basis of scheme one, using the increase power turbine after turbine 2
Technology further recycles the exhaust energy of internal combustion engine, but the requirement of this scheme enters the gas pressure superatmospheric of power turbine
Power, therefore, when entering the exhaust gas pressure of power turbine close to atmospheric pressure, the acting ability of power turbine is limited, Wu Fajin
One step recycles the exhaust energy of internal combustion engine.
