China's first low-speed, dual-fuel, independently-developed marine engine was officially delivered on Friday in Zhenjiang City, east China's Jiangsu Province.

A dual-fuel engine refers to an engine that can use both oil and natural gas as fuel, switching between oil and gas modes.

As China's first independently-developed 5,000-kilowatt marine dual-fuel engine in accordance with international standards, the model CX40DF is more economically efficient with higher thermal efficiency, which can effectively reduce fuel consumption and provide a more stable and safe performance.

The successful delivery of the model marks a step forward for China in building up its independent development capabilities in the marine power industrial chain.

"The delivery of CX40DF marks the initial establishment of a research and development technology system for marine low-speed engines in China. After mass application, we no longer need to follow the production mode with foreign patent licensing but can realize independent research and development," said Liu Bo, a technical expert at China State Shipbuilding Corporation (CSSC) Marine Power Co., Ltd., the company that developed the engine.

According to Liu, the first engine will be installed on a 9,500-cubic-meter multi-purpose gas carrier. Because it mainly uses natural gas as fuel, the engine's carbon emissions are more than 20 percent lower than that of diesel engines.

"This model has a wide range of applications and can provide green power for 10,000 to 30,000-ton gas carriers, tankers, container ships, and dry bulk carriers. It has a good market prospect," said Li Cheng, chairman of CSSC Marine Power Co., Ltd.
