It’s an eight cylinder diesel engine that still produces  15,000kw (22,500 hp) and was the largest in the world from 1932 to 1962.  The following video shows the engine starting up. <iframe width="560" height="315" src="https://www.youtube.com/embed/pwvS8_H5rKs" frameborder="0" allowfullscreen></iframe> The World’s Largest Diesel Engine Today   The following is a summary of information provided by  Wartsila-Sulzer, the Finnish manufacturer of the largest diesel engine  in the world today. The engine is used on the Emma Maersk cargo ship  pictured below. A full line-up of Wartsila Marine Diesel Engines can be  found <a href="http://boatdiesel.com/Engines/Wartsila/Wartsila.cfm" target="_blank">here</a>.  <a href="http://www.industrytap.com/worlds-largest-diesel-engines-past-present-video/25044/emmamc3a6rsk003" target="_blank"><img src="http://www.industrytap.com/wp-content/uploads/2014/12/600x399xemmamc3a6rsk003-1024x682.jpg.pagespeed.ic.0H9PXy_Z93.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>World’s Largest Diesel Engine The largest in the current line of <a href="http://www.wartsila.com/en/engines/low-speed-engines/RT-flex96C" target="_blank">Wartsila-Sulzer</a>   diesel engines is a turbocharged two-stroke low-speed engine, used to  power giant supertankers and cargo ships worldwide that run on heavy  fuel oil. The largest version is 14-cylinders and is 44.3 feet (13.5m)  high and 87.25 feet (25.6m) long, weighs over 2,300 tons and produces  80,080 kW. The engine uses 140 bar compression or over 2,000 pounds per  square inch on the piston, about 1,091 tons of pressure on the piston  /rod at the top of the compression stroke.   The engine uses “rail technology” that has done away with the  traditional camshaft, chain gear, fuel pumps and hydraulic actuators,  thereby providing better performance, lower revolutions per minute,  lower fuel consumption, and lower emissions.   The engine has crosshead bearings and an always-vertical piston rod  that provides a tight seal under the piston. As a result, the  lubrication of the engine is split: the cylinders and the crankcase use  different lubricants, each being specialized for an dedicated to its  role. Cylinders are lubricated by continuous, timed injection of  consumable lubricant which is formulated to protect the cylinders from  where and to neutralize the acids formed during combustion of the  high-sulfur fuels. The crosshead design reduces sideways forces on the  piston, keeping diametral cylinder line where in the order of only about  0.3 mm per 1000 hours.   The descending piston is used to compress incoming combustion air for  the adjacent cylinders which also serves to cushion the piston as it  approaches bottom dead center to remove some load from the bearings. The  engine is unit flow-scavenged by way of exhaust valves that are  operated by electronically-controlled, common-rail hydraulics, thus  eliminating the camshaft. <a href="http://youtu.be/awJIvdzL5dE" target="_blank"><iframe width="560" height="315" src="https://www.youtube.com/embed/awJIvdzL5dE" frameborder="0" allowfullscreen></iframe></a> World’s Largest Diesel Engine Tomorrow   In the pipeline is the MV CSCL Globe, the world’s largest container  with a capacity of 19,000 TEUs that will be propelled by a MAN B&W  12S90ME-C Mark 9.2 low-speed two-stroke engine that produces 69,720 kW @  84 rpm and is 56 feet (17.2 m) tall and 193.5 feet (59m) long. This  makes it taller and longer than the Wartsila engine mentioned above.  This ship will be put into service in 2015.   <a href="http://www.industrytap.com/worlds-largest-diesel-engines-past-present-video/25044/china_shipping" target="_blank"><img src="http://www.industrytap.com/wp-content/uploads/2014/12/635x447xChina_Shipping.jpg.pagespeed.ic.nZzSDGYL1E.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>World’s Largest Diesel Engine</blockquote>
