Q1/B: A four-cylinder four-stroke SI engine has an output of 65 kW at 2500 rpm. A Morse test is carried out on this engine and the cylinders cut out in the order 1, 2, 3, 4 with the corresponding brake torque readings of 175, 172, 170 and 171 N.m, respectively. Calculate the mechanical efficiency of the engine.
