1. A four-stroke diesel engine has six cylinders, each of diameter of 127 mm and 149 mm stroke. At 1200 r/min the average brake mean effective pressure is 6.9 x 105 Pa and the fuel consumption is 18.8 kg/h. The energy release during compression of 1 kg of fuel is 44200 kJ/kg. The pressure compression ratio is 14:1. Determine: (a) The brake power (b) (c) The brake torque The brake thermal efficiency (d) The fuel consumption (e) The brake thermal efficiency ratio referred to the ideal constant pressure air cycle. For air take y = 1.4 [78.14 kW; 621.8 N.m; 33.86%; 0.241 kg/kWh; 64%] 1. A four-stroke diesel engine has six cylinders, each of diameter of 127 mm and 149 mm stroke.
