"
The most powerful and most efficient piston prime-mover in the world today. Bore of just under 3'2", stroke of just over 8'2". Available in 6 through 12 cylinder versions (all inline). Maximum continuous power of 89,640 HP is obtained at 100RPM with the 12 cylinder version. Maximum economy power of 53,244 HP is obtained at 90 RPM. The engine exceeded 100,000 horsepower during overspeed testing (all of 101.5 RPM!) while under test at Japan's Diesel Union works (who also built the first engines and from who these pictures are taken).
Fuel consumption at maximum power is 0.278 lbs/HP/hour (BSFC). Fuel consumption at maximum economy is 0.260 lbs/HP/hour. The latter figure exceeds 50% thermal efficiency (i.e. more than 50% of the fuel going into the engine is converted to power). Compare with automotive and small aircraft spark-ignition engines with BSFCs in the 0.40-0.60 range and 25-30% thermal efficiency. Engine weight exceeds 2000 tons in the 12 cylinder version (the crankshaft alone exceeds 300 tons).
Note that, even at its most efficient power setting, the 12 cylinder version will consume nearly 1,660 gallons of heavy fuel oil an hour!"
