The diesel that shook the world. Why do ship engines dwarf every car on Earth? The Wärtsilä RT-flex96C is the world's largest diesel, built for container ships. It's 89 feet long, 44 feet high, and produces over 100,000 horsepower. Just one cylinder is bigger than an entire car engine, and it burns 250 tons of fuel per day.
