Winterthur Gas & Diesel’s 12X92DF dual engine has been recognized by Guiness World Records as the most powerful Otto-cycle engine ever built.
In tests carried out at engine builder CSSC-MES Diesel Co (CSSC-CMD) in China and verified by Guiness World Records, the 2,140-tonne engine demonstrated a power of 63,840 kW at a speed of 80 rpm.
The WinGD 12X92DF powers the series of nine 23,000 TEU LNG-fueled containerships ordered by Frances CMA CGM, the first of which, CMA CGM Jacques Saadé, entered service last year. The ships’ 18,600 cu.m fuel tanks contain enough liquefied natural gas (LNG) to enable themt o sail complete Asia to Europe round trips.
“The future uptake of LNG as a marine fuel is being driven by large merchant vessels with two-stroke engines, where the savings – and the environmental benefits – are the greatest,” said WinGD CEO Klaus Heim. “We are delighted with this achievement, which was made possible by CMA CGM’s strong vision and close cooperation with engine builder CSSC-CMD and Bureau Veritas. The 12X92DF is not just the biggest dual-fuel engine in our portfolio – it is now officially the most powerful of its type in the world.”
Specifically, the engine has been recognized as the “Most powerful marine IC engine (Otto cycle) commercially available.”
Guiness World Records Vice President, Neil Foster said of the achievement: “The WinGD marine internal combustion engine is thoroughly deserving of its Guiness World Records title. Records for engineering excellence never fail to fascinate, and this title is testament to the skill of the team at WinGD that had the vision and dedication to deliver the technology behind the title.”
The 12X92DF draws on design and field experience earned through an installed base of more than 100 X-DF engines logging nearly one million running hours with almost 400 X-DF engines on order.
