Question
During a test on a 5-cylinder four-stroke IC diesel engine with a cylinder bore and stroke length of 240 mm and 297 mm respectively, running at 468 r/min, the following results were obtained: Mass on Dynamometer mass hanger (arm length = 0.825 m) 205 kg Indicated mean effective pressure 528 kPa Fuel consumption (with Qnet,v = 39.8 MJ/kg, %3D density = 0.944 kg/l) 6 ml/s Take acceleration due to gravity as 9.81 m per square seconds Calculate the brake thermal efficiency_ _in decimal form to 3decimal places.
