Worlds Largest Diesel Engine

This is the world’s largest engine! This Is What 109,000 HorsePower Looks Like. Meet The Biggest Engine In The World, The Wärtsilä RT-flex96C.

This massive monster was created in Finland. If you are wondering what it’s used for, it’s used for the largest cargo ship known to man.

Let’s talk a little about the actual engine components.

  • It has 14 cylinders.
  • It can produce a whopping 80,080 Kilowats of power, enough to power an entire suburban town.
  • it’s 44 feet tall, 90 feet long, and weighs 2,300 tons.
  • It redlines at 102 RPM, but has enough torque to easily rip a tank into pieces.
  • It’s used in a cargo ship that carries 11,000 20ft cargo containers.
  • It has a turbo, and it’s bigger than a large SUV.

It carries over 11,000 20foot long containers at a speed of 31 knots (35 mph). Think about that for a second…This ship will carry itself which weighs over 2,300 tons, and then carry 11,000 20foot cargo crates full of anything from food exports to vehicles. And it will do this going 35 mph! Hell my first cars top speed was 60mph and it only weighed about 1% of what this thing weighs.

Shipping goods from China to the U.S. is big business. And when we say big, we’re talking 1,300-foot-long ships that weigh 170,974 tons. This cargo ship can carry 11,000 20-foot shipping containers at a breakneck speed of 31 knots. The containers themselves carry anything from food products to fully assembled vehicles.

All of this is possible thanks to the massive diesel engine of the 109,000-horsepower Wärtsilä-Sulzer RTA96-C, which first set sail in the Emma Mærsk in 2006.

That’s a lot of motor to think about. Imagine how big the camshaft is, oh wait, it doesn’t have one. That’s because it has a turbocharged two-stroke that features common rail tech that utilizes a high-pressure fuel rail to supply the fuel to individual solenoid valves (that are bigger than your car).

So far there are only 25 of these massive engines delivering cargo from China to USA. But, since these can do it in four fewer days than their competitors, another 86 have been ordered and will be in use by 2025. That is, unless Elon Musk gets involved 🙂
