A hybrid vehicle has SI engine that operates on an air standard four-stroke Miller cycle. The intake valves close later, resulting cycle 6'-7-8-7-2-3-4-5-6 as shown in the figure below. The cylinder conditions are 45 C and 130 kPa at the start of the compression. The maximum temperature during the cycle is 3600 K. Compression ratio rc = 9.5, and expansion ratio re = 12. Determine (i) (ii) Heat input during the combustion process. [kJ/kg] Work produced during expansion stroke. [kJ/kg] (iv) Work consumed during compression stroke. [kJ/kg] (iii) Temperature [K], pressure [kPa], and specific volume [m/kg] at state points 7, 2, 3, and 4.
