[Watch] The World’s Largest Gas, Dual-fuel Engine Construction


Winterthur Gas & Diesel (WinGD) has shared a time-lapse video of the construction of a 12X92DF engine built by CSSC-MES Diesel in Shanghai, reports Riviera Maritime Media.

This monstrous 12-cylinder X92DF engine is destined for use in one of the largest container ships ever ordered.

The 12X92DF engines will power CMA CGM’s series of mega container ships, each with a record capacity of 22,000 TEU.

Environmental sustainability

The Switzerland-based company said the engines will bring “a new level of environmental sustainability to the containership segment.”

Rated 63,840 kW at 80 rpm, the engine weighs over 2,100 tons. The low-pressure dual-fuel technology is said to enable stable combustion, high fuel efficiency and low noxious and greenhouse gas emissions typical of lean burn gas combustion.

Sulphur and Nitrogen emission regulations

X-DF engines comply with IMO Tier III limits on NOx in gas mode and IMO Tier II in liquid fuel mode, both without EGR or SCR.

They would comply with the upcoming emissions regulations due to the low NOx and SOx emissions from burning LNG in the X-DF engine.
