World’s Largest And Most Powerful Diesel Engine

Have your first look at Wärtsilä RT-flex96C, the world’s largest and most powerful diesel engine in the world today.


Yes, isn’t it awe inspiring and amazing? Manufactured by a Finnish company known as Wärtsilä, this engine is capable of producing 80080 KW power, enough to charge an entire suburban town. The magnificent engine weighs an astounding 23,000 tons. It is a two-stroke turbo charges low speed engine.

Are you wondering where exactly will this huge intimidating machine be used? For a long time now, shipping has proved to be the most efficient form of trade. Just for your information, these massive trading ships weigh thousands of tons and go at decent speeds of more than 35 knots. To provide such huge engine power, the engine has to be robust. The Wärtsilä RT-flex96C will provide all that power and more. The engine has been put into use in September 2006 at Emma Mærsk.

The huge engine has 14 built-in cylinders that consume about 6.5 ounces of diesel in one cycle. Each cylinder is capable of producing about 5700 kW of energy. The design is similar to the RTA96C engine however, the traditional camshaft, hydraulic actuators and pumps have been replaced by the all new state-of-the-art rail technology. The engine speed varies from 22-102 rpm.

The efficient Wärtsilä RT-flex96C can consume 170 g/kWh and has bore of 960 mm. It is also environment friendly and does not release excessive amounts of harmful GHG emissions. The engine is highly efficient and is considered the largest reciprocating engine in the world.

The Wärtsilä RT-flex96C is undoubtedly a wonder of modern engineering. The huge machine is capable of powering any size of ships and its 14 built-in cylinders cater for huge amount of power demands. The remarkable engine is 44 feet tall and 90 feet long.

The ships that transport goods from China to the U.S. are usually Huge. And when we say huge, we are talking about ships weighing 180,000 tons each and 1300 feet or more in length. A lowly, measly turbo engine cannot even move these gigantic ships. The Wärtsilä RT-flex96C diesel engine produces 109,000 horsepower of energy that runs such ships. Currently, there are about 25 of these huge engines out there in our oceans and 86 more are coming soon. The improved fuel economy, longer life spans and better engine performance ensure bright future prospects for the huge Wärtsilä RT-flex96C engine.
