A CI engine operating on the air-standard Diesel cycle has cylinder conditions at the start of

= 0.8 compression of 65°C and 130 kPa. Light diesel fuel is used at an equivalence ratio of with a combustion efficiency Compression ratio is r_c=19.

Calculate:

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

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

(c) Cut-off ratio.

(d) Indicated thermal efficiency. [%]

(e) Heat lost in exhaust. [kJ/kg]
