An ideal Diesel engine operates on 0.063 lbm of air with a suction state at 14 psia and 140 °F. The pressure at the end of compression is 458 psia and the volume at the end of heat addition process is 0.13 ft°. Using air properties (R=53.34 ft-lbf/lbm-R, k=1.4, Cp =.24, Cv=.1714 Btu/lbm-R), determine compression ratio, percentage clearance, Qa, Qr, Thermal Efficiency, mean effective pressure.
