Akasaka 8 U 50 Engine
The engine is built to operate at such a speed that it doesn't require to be coupled to a re-
duction gearbox. The Akasaka 8U50 engine is a trunk piston medium- speed unit which is
produced in eight in- line cylinders and develops its rating of 813 b.h.p./cylinder at 340
rev/min. This machine is a development of Akasaka's earlier 6U50 machine which, though of
less cylinders, was rated at 917 bhp/cylinder at 340 rev/min.
The Akasaka 8U50 engine is a four- stroke machine with two inlet and two exhaust
valves which are actuated by rockers. The machine operates on low- grade heavy fuel and, be-
cause of that, the exhaust valve seats are arranged for fresh water cooling. The pistons are of
the built- up type with an alloy steel crown and cast iron skirt; cooling is by system lubricating
oil. The entire construction of the engine including the bed plate, cylinder block and cylinder
covers, is of cast iron. The bed plate is cast in two pieces and clamped together by horizontal
stay bolts at the centre of No, 6 cylinder. The crankshaft is of the solid type, balance weights
are fitted on each crank web. It is a turbo chargers are mounted one on either end of the engine.
