The worlds biggest engine is the Wartsila-Sulzer RTA96-C. It is a turbo charged two-stroke diesel engine 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 is confusing is why they haven't actually built the ship around the engine? How they actually get this 2000-ton engine out of the factory and installed into a ship is mind boggling.

These large engines are designed to power the worlds super oil tankers and large container ships. They are built to the ship owners preferences. They usually request an engine construction of a single unit and single propeller design for ease of maintenance, and not surprisingly any later troubleshooting. A single unit and single screw design has also proved over time to have a longer life span than double or even quad screws. 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.
Speaking of 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.

-------------------------

The Mathematical calculation : 1,660 gallons/per hour = 39.5 barrels of crude oil/used per hour = $2,844. These figures are worked out from the basis of crude oil @ $72 a barrel*.
$2,844 every hour the engine runs or 27.6 Gallons which is $46.00 every minute or 76 cents a second ! That is of course if the ships buy oil at trade price...if not then these figures are the absolute minimum.

you started it !
the 2 stroke Diesel Engine .
my favorite engine Ever ,
funny how when ever one need extreme Power they all cam back to the basics .
the firsts Diesel engines where 2 stroke.
it is still to date the most's energy efficient inner combustion engine.
Did you know that in the early 90 there was a boat sport , very interesting ,
the F3 speed racers world wide , with a major restriction for the amount of energy (diesel ) allowed into the engine.
they where running a V12 cylinders under cubic 2 stroke diesel .
under cubic is when (unlike Harley for example) the travel of the piston is less then its dimension , those pistons then became oval ,
those engines where running at about 16,000rpm ,
its was a test field that led to many of the Principals used for today car diesel , and automatic transmission.
and yet the same design will work on your case with a 10 foot piston travel ,at 190 rpm ...

Yea, that is one big motor. I bet it could power a small city
