WinGD has received its 100th order for Variable Compression Ratio (VCR) technology.
This technology optimizes combustion for X-DF dual-fuel engines depending on the fuel type and load.
The unique technology was introduced in June 2023 and is already a popular choice for dual-fuel engine orders, especially in the LNG carrier category.
A shipowner from the Middle East has ordered four LNG tankers from a Korean shipyard, thereby reaching an important milestone.
These orders join numerous others that have made X-DF engines and VCR technology the preferred choice for the LNG carrier category over the past year, with additional orders coming from the pure car and truck carrier, bulk carrier and container ship categories.
In total, about ten owners have chosen the new technology as an option for their X-DF engines.
WinGD Sales Manager Volkmar Galke: “Over one hundred orders for our variable compaction systems
Technology called VCR in the first year is a phenomenal achievement and shows the strong market
Interest in technologies that both reduce the environmental impact of gas engines and
Eliminate any compromise in diesel performance.
“We are grateful to these pioneers and see even greater opportunities for the industry to benefit from this unique engine technology in the future.”

VCR technology adjusts the engine’s compression ratio depending on the fuel type, engine load and combustion behavior.
This means that when running on diesel, higher compression ratios can be used, increasing efficiency. Additionally, when using LNG, compression can be adjusted to improve performance and reduce emissions.
The simple hydraulic solution represents the first dynamic change of the compression ratio in a marine engine.
WinGD’s second X-DF2.0 technology, VCR, is an improvement on their current X-DF dual-fuel engine architecture.

The original innovation, Intelligent Control by Exhaust Recycling (iCER), was well received and has been used in the majority of LNG tanker orders over the past two years.
WinGD’s latest tests show that X-DF engines with iCER and VCR have lower fuel consumption and emissions than other low-pressure engine technologies.
At the system level (including main and auxiliary engines and fuel supply), vessels can achieve a similar fuel consumption and emission profile to vessels with high-pressure two-stroke diesel engines, while achieving an investment advantage due to the low cost of the required auxiliary system.
Thanks to the innovative technology and reliable operating experience of the X-DF engine platform of over 7.5 million operating hours, the X-DF engines are the clear market option for LNG carriers while remaining competitive compared to high-pressure engines in other vessel segments.
CMA CGM recently tested WinGD’s VCR technology on board one of its vessels.
