The 109,000-horsepower Wärtsilä-Sulzer RTA96-C, which first set sail in the Emma Mærsk in 2006, weighs in at a rotund 2,300 tons, and it's 44-feet tall and 90-feet long.
The bore of this little putter is over three feet.
At maximum economy the Wartsila-Sulzer RTA96-C motor exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
For comparison, automobiles have about 25% thermal efficiency and the modern diesel electric locomotives are in the 40% range.
