- Hanwha Engine has produced the world’s first X-DF engine with variable compression ratio (VCR) technology for LNG carriers.
- The VCR system, developed by WinGD, enhances fuel efficiency and lowers carbon dioxide emissions.
- It reduces methane slip by 30–50% compared with existing technologies.
- Hanwha Engine marked the achievement with a commemorative event attended by industry leaders.
On the 29th, Hanwha Engine revealed it had achieved a milestone in ship engine manufacturing by producing a variable compression ratio (VCR) engine for LNG carriers powered by X-DF dual-fuel technology, according to ChosunBiz.
Reducing Methane Slip with Next-Generation Solutions
VCR technology is regarded as a next-generation solution for eco-friendly propulsion. By adjusting the compression ratio in real-time according to engine operating conditions, it improves fuel efficiency and lowers carbon dioxide emissions. Notably, the system also reduces methane slip—unburned LNG fuel released into the atmosphere—by 30% to 50% compared with existing methods.
Commenting on the achievement, CEO Yu Moon-ki stated that the successful production of the VCR-applied X-DF engine is more than a technological advancement; it represents a major step toward accelerating the industry’s transition to sustainable operations. He emphasized Hanwha Engine’s commitment to contributing to the marine environment through the continued development of eco-friendly technologies.
