In a reciprocating engine which has four cylinders in line, the reciprocating masses are each 0.5 kg per cylinder. The stroke is 120 mm, and the connecting rods are 450 mm long. The firing order of the engine is 1-4-2-3 and the cranks are set at 90° to each other. The cylinders are spaced 140 mm apart and the engine speed is 2000 rev/min. Find: 1.The maximum out-of-balance primary and secondary forces. 2. The maximum out-of-balance primary couples.
