Consider a spark ignition combustion engine with two possible configurartion for turbocharging. Configuration A is conventional turbocharging. Configuration B is a new propsed configuration using a vapor Rankine power cycle. Assuming a typical engine exhust temperature of 650 C, and assuming a typical exhaust mass flow rate and exhaust pressure for an SUV-six-cylinder engine,propse three different vapor cycles for Configuration B using different vapors. Compare the performance of each vapor cycle against the conventional Configuration in terms of gain in engine intake pressure ratio. For pumps, turbines and compressor use 85% isentropic efficiency, for heat exchangers use an effectiveness of 0.8 and assume 5% pressure lose. All specific heats must be treated as varying with temperature
