When I first saw this image I thought it was a Photoshop trick, but it seems to be an actual engine.
In Autoblog’s article about the World’s Largest Diesel Engine, where I saw this, they tell the story of the large engines used for cargo ships.
The turbo diesel engine pictured has 14 cylinders that produce a whopping 109,000 horsepower. I think it’s interesting to see something made on such a large scale.
