  1. The 3.4 L British Jaguar XK four-stroke-cycle automotive engine has 6 cylinders in line, 8.306 cm x 10.592 cm size, a compression ratio of 8 and develops 156.7 kW at 5500 rpm. For the ideal cycle, the conditions at the beginning of compression is 101.35 kPa, 54.4 0C. At 5500 rpm the brake thermal efficiency and the volumetric efficiency are 30% and 78% respectively. Solve the following:

a) Volume Displacement, m3/s

b) Mass of air, kg/s

c) Maximum Pressure and Temperature

d) Brake Engine Efficiency (K=1.32)

e) A:F ratio (HV = 44,432 kJ/kg).
