An on SI engine operates an air-standard 45 Miller cycle with turbocharging. The intake valves close early, resulting in cycle 6-7-1-7-2-3-4-5-6. Air-fuel enters the cylinder at 70 C and 145 kPa, and heat in by combustion equals 1750 kJ/kg. Compression ratio is 7.8 and expansion ratio 10, and exhaust pressure is 110 kPa. Calculate: a) Pressure and Temperature at all states of the cycle. [C, kPa]. b) Work produced during expansion stroke. [kJ/kg]. c) Work produced during compression stroke. [kJ/kg).
