The Most Powerful Diesel Engine in the World
When you think of diesel engines, your mind may automatically go to vehicles like cars, trucks, and trains. But what about the engine that's needed to power container ships?
The most powerful diesel engine, also one of the largest to exist, the Wartsila RT-flex96C is used in container ships and weighs around 2,300 tons.
It has a maximum power of up to 109,000 horsepower to move a vessel weighing approximately 200,000 tons.
As the first 14-cylinder engine, it was created in 2006 and used to give freight ships enough power to travel great distances.
One of its biggest advantages is that the Wartsila RT-flex96C has excellent fuel efficiency, ensuring cargo ships won't be stuck at sea.
Wartsila-Sulzer RT-flex96C
In addition to its use in cargo ships, the Wartsila RT-flex96C is a high-efficiency diesel engine that can be used for heavy-duty applications such as powering mining trucks, aircraft engines, construction equipment, marine vessels, and power plants.
It also features a variable engine speed drive system which allows the engine to be operated efficiently at different speeds.
At its peak, the RTA96C-12 can produce up to 108,920 horsepower (at 102 RPM) and has an incredible fuel consumption rate of just under 50%.
This powerful RTA96C engine is also the size of a multi-story building, coming in at approximately 44 feet tall and 90 feet long.
And the amazing torque curve on this engine has massive power across a wide speed range, enough to tear through an industrial vehicle like a tank with ease.
The Wartsila RT-flex96C is one of the most efficient engines for saltwater environments.
It is a direct-drive engine that does not require a gearbox, but it requires about six people to operate it simultaneously because of its size. It is equipped with a single-cylinder head and four valves per cylinder.
The engine uses a turbocharger to increase its efficiency. It is made of cast iron and aluminum alloy and is reliable, requiring minimal maintenance.
Despite its large scale, the engine isn't too difficult to maintain. Engineers maintain it at regular service intervals, doing oil changes, checking for leaks or abnormalities, power output checks, and checking peak cylinder pressures.
