China State Shipbuilding Corporation Limited (CSSC) on Friday (2 April) said the first low-speed dual-fuel marine engine independently developed by CSSC’s subsidiary China Shipbuilding Power Group has been officially delivered in Zhenjiang, Jiangsu.
CSSC noted CX40DF is currently the world’s smallest bore marine low-speed dual-fuel engine (Otto cycle) engine. It utilises liquefied natural gas (LNG) as its main fuel.
Compared to diesel engines, its carbon emissions are reduced by more than 20% and it is China’s first 5000-kilowatt marine low-speed dual-fuel engine developed in accordance with international standards. The team took five years from the design stage to delivery of the engine.
To build the engine, the team conducted scientific research on new technologies such as pre-chamber ignition, dynamic oxygen concentration control, integrated gas pressure regulation, and low-emission premixed combustion.
They also managed to resolve a number of technical problems, including dynamic oxygen concentration. CSSC said the control technology is the first application in the world, increasing the power of this model by 4% and significantly reducing the fuel/gas consumption rate.
For the first time, CX40DF’s electronic control system, turbocharger, oil mist detector and other core components were independently produced, with 80% of its parts produced locally.
Previously, low-speed engine components were supplied by international brands which meant that more than 10% of its sales price would go towards patent fees.
CX40DF’s successful delivery is a milestone in China’s maritime industry where it is becoming increasingly independent even for high-end technology.

‘Bunker barges operate in very local areas so these vessels call at port very often which means it will be a good fit for women with families,’ states Elpi Petraki, President of WISTA International.
“Our Singapore branch is under preparation and is expected to start business at the republic before June 2023,” Managing Director Darcy Wong tells bunkering publication Manifold Times in an interview.
Development to supply B35 biodiesel blend officially takes effect on 1 February; local bunker suppliers will be able to deliver updated spec within March onwards, once current stocks of B30 avails run out.
VPS, Global Centre for Maritime Decarbonisation, Wilhelmsen Ship Management, and INTERTANKO executives offered a multitude of perspectives to 73 attendees during the VPS Biofuels Seminar, reports Manifold Times.
