China Shipbuilding Heavy Industry News, on December 4, Dalian Marine Diesel Engine Co., Ltd. and the world-renowned ship power research and development organization Wärtsilä Group signed an agreement to jointly develop a new generation of X92 marine mainframe. This means that China Ship Power will rewrite the history of domestic high-speed low-speed diesel engines by domestic machine manufacturers through the purchase of foreign production licenses. Mr. Wu Shu, general manager of Dalian Shipai, and Martin Wenley, general manager of Wärtsilä Switzerland, signed the agreement.
It is reported that the new generation X series mainframe adopts electronically controlled common rail technology, which can reduce fuel consumption by 10% compared with existing models. The IMO Tier II standard is met in terms of emissions, and the Tier III standard can be met by continuing to upgrade. At present, the X series mainframe has been independently developed by Wärtsilä to X35 to X72 models, and the X72 model is being built in Dalian Shipwood. The maximum output power of the X92 mainframe to be developed will reach an unprecedented 6130 kW (8330 hp), even exceeding the maximum single-cylinder output power of Wärtsilä's current largest RT-flex96C mainframe of 5,720 kW, which is difficult for any organization to bear alone. R&D is indispensable, and it is urgent to select a host manufacturer with strong R&D capabilities and excellent construction experience to jointly develop. Among the dozens of machine manufacturers in the world, Dalian Shipwood stands out.
The X92 mainframe will be combined with electronically controlled common rail and extra long stroke. The design parameters will make the cabin more compact, and the speed and power range provided will meet the ship's diversity selection requirements, achieving the lowest daily fuel consumption and the most economical propulsion scheme. Has a wide range of applicability. Take the 12-cylinder X92 mainframe as an example, the power can reach 100,000 horsepower. This model will mainly adapt to large and super large container ships, and also provide complete power solutions for special ship types, and has strong competitiveness in the use of marine power performance.
