- 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).
