Q5: A high speed Diesel engine working on ideal Dual combustion cycle takes in airat a pressure of (1 bar) and temperature of (50 °C) and compresses it adiabatically to(1/14) of its original volume. At the end of the compression the heat is added in sucha manner that during the first stage the pressure increases at constant volume totwice the pressure of the adiabatic compression, and during the second stagefollowing the constant volume addition, the volume is increased twice the clearancevolume at constant pressure. The air is then allowed to expand adiabatically to theend of the stroke where it is exhausted, heat being rejected at constant volume.Calculate (a) the temperature at the key points of the cycle, and (b) the ideal thermalefficiency. Answers [(a) T2-930K, T3-1860K, T4-3720K, T=1710K (b) 60.8 %]

Efficiency = 0.608 × 100 = 60.8%
