The world’s biggest engine is the
Wartsila-Sulzer RTA96-C. It is a turbo charged two stroke diesel engines and it
is the most powerful and efficient low revolution engine in the world today.
The Wartsila-Sulser is manufactured
by the Aioi Works in Japan and is part of Japans Diesel United Ltd engine
manufacturers.
Below is an 89 foot long 44 foot
wide 12 cylinder engine, literally as big as a house! What I find confusing is
why they haven't actually built the ship around the engine? How they actually
get the 2000 ton engine out of the plant and more over install an engine of
this size into a ship makes the mind boggle.
These engines are built in 6, 8, 10,
12 and 14 cylinder configurations. All the engines are straight or 'inline'.
The diameter of each cylinder is 3 foot 2 inches with a stroke of 8 foot 2
inches. The 12 cylinder version weighs in at 2000 metric tons and delivers 90,000
Horse Power at 100 Revs per minute, with best fuel economy at 53,244 HP at 90
Rpm.
When I mention economy, the 14 cylinder engine for example with a displacement of 25,480 Litres ( 1.56 million cubic inches ) burns up 1,660 gallons of crude ("bunker") oil every hour.
