An eight-cylinder, four-stroke engine has a pisto diameter of 60 mm. The piston covers a combined) distance of 400 mm through four strokes. The rated speed of the piston is 46.67rps and it is tested at this speed against a brake which has a torque arm of 350 mm. The net brake load is 150 N, the mass flow rate of fuel is 0.88kg/s and it has a lower calorific value, Qnetv, is 44 MJ/kg. A Morse test is carried out and the cylinders are cut out in the order 1, 2, 3, 4, 5, 6, 7, 8, with corresponding brake loads of 124.9 Ν, 129 Ν. 121 Ν, 128.5 N, 131 N, 126.3 Ν. 125.1 N, 127 N, respectively.
