The World-Record-Holding Wartsila 31 Diesel Engine

March 11th, 2018 9:31 pm

The World-Record-Holding Wartsila 31 Diesel Engine
The folks at Guinness World Records recently named the gigantic Wärtsilä 31 engine the "Most Efficient 4-Stroke" and, according to Roger Holm, Senior Vice President, Engines, Wärtsilä Ship Power, "it clearly redefines efficiency." The large diesel stands at more than 13 feet tall and is available in configurations including V-8, V-10, V-12, or V-16, and it uses just 165 grams of diesel per kilowatt/hour while meeting modern pollution requirements. It's designed for use in marine vessels, including container transporters, ferries, and cruise ships, where efficiency and emissions compliance are extremely important.

The largest of the bunch is the V-16, which has a huge displacement of 519.3L thanks to a wide bore of 12.2 inches and a long stroke of 16.9 inches for each cylinder. It creates 13,088 hp at just 750 rpm (818 hp per cylinder), which is the equivalent of 9.8 megawatts of power-almost enough to run the average American home for an entire year!


In addition to sipping fuel, the engine is also designed to save time and money for owners with a modular design that allows individual cylinder components to be swapped out. The first overhaul is not scheduled until five years or 32,000 hours of operation, and the first maintenance interval is not required until 8,000 hours (compared to just 2,000 hours for engines with similar power output). If the Wärtsilä name sounds familiar, then you've probably heard about the company's other record-breaker-the "World's Largest Marine Engine"-the RT-flex96C that stands more than 44 feet high and weighs more than 2,500 tons.
