On 16 September 2021 Yanmar received an order for dual fuel 6EY22ALDF engines which will be used to power generators on board a LNG-fueled large coal carrier to be operated by Mitsui OSK Lines Ltd. The coal carrier will be built by Namura Shipbuilding Co., Ltd.
Emission regulations in the marine sector are becoming ever more stringent, with LNG vessels being adopted globally as a means of reducing environmental impact. As this trend has progressed in recent years, dual fuel engines have attracted ever more attention.
Their ability to run on both diesel and environmentally friendly LNG allows them to satisfy International Maritime Organization (IMO) Tier 3 regulations whilst also reducing greenhouse gas (GHG) emissions.
YANMAR will continue its efforts to reduce marine engines’ environmental impact and develop clean marine powertrains to provide optimal solutions that meet the needs of our customers.
With features such as load fluctuation tracking and high thermal efficiency, in addition to precision air-fuel ratio control technology, 6EY22ALDF engines always maintain optimum combustion, enabling them to deliver stable, highly reliable operation.
The engine has a rated power of 800kW, six cylinders and a cylinder bore x stroke of 220 x 320mm.
Founded in Osaka, Japan in 1912, Yanmar was the first ever to succeed in making a compact diesel engine of a practical size in 1933. A pioneer in diesel engine technology, Yanmar is a global innovator in a wide range of industrial equipment, from small and large engines, agricultural machinery and facilities, construction equipment, energy systems, marine, to machine tools, and components.
