I saw this and thaught that it was interesting so Wartsila-Sulzer RTA96-C Turbo charged two stroke diesel built by Aioi Works of Japans Diesel United, Ltd 14 cylinder Total engine weight= 2300 tons ( the crank weighs 300 tons alone!) Length= 89 feet Height= 44 feet Maximum power= 108,920 hp at 102rpm Maximum Torque= 5,608,312lb/ft at 102 rpm The cylinder bore is just under 38" and the stroke is just over 98" each cylinder displaces cubic inches (1,820 Liters) and produces 7,780 hp total displacement comes out to cubic inches (25,480 Liters). Fuel consumption at maximum power is 0.278 lbs/hp/per hour (brake specific fuel consumption). Fuel consumption at economy is 0.260 lbs/hp/per hour. the engine exceeds 50% thermal efficiency. THat is more than 50% of the energy in the fuel converted to motion. For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40 lbs/hp/per hour range and 25-30% thermal effiency range Even at its most efficient power setting, the straight 14 consumes 1,660 gallons of fuel an hour!
