An in-line six, 3.3-liter CI engine using light diesel fuel at an air–fuel ratio of operates on an air-standard Dual cycle. Half the fuel can be considered burned at constant volume, and half at constant pressure with combustion efficiency Cylinder conditions at the start of compression are 60°C and 101 kPa. Compression ratio r_c=14:1.

Calculate:

(a) Temperature at each state of the cycle. [K]

(b) Pressure at each state of the cycle. [kPa]

(c) Cut-off ratio.

(d) Pressure ratio.

(e) Indicated thermal efficiency. [%]

(f) Heat added during combustion. [kJ/kg]

(g) Net indicated work. [kJ/kg]
