An engine is operating in dual combustion cycle; the maximum pressure is $66$ bar. Calculate $q_{in},q_{\text{o}\text{u}\text{t}}$ and the thermal efficiency for this engine when the pressure and temperature at the beginning of the compression process are $1\mathrm{.}03$ bar and $20\mathrm{.}3C,$ respectively. The compression ratio for this engine is $17\mathrm{.}9.$
