Swiss engine designer, WinGD has confirmed that the performance of its X-DF2.0 engine technology has surpassed initial expectations in terms of fuel savings achieved.
Optimised engine settings on WinGD’s X-DF2.0 second-generation dual-fuel engine platform achieved fuel savings of up to 8% in gas mode and up to 6% in diesel mode during recent tests at CMD (CSSC-MES Diesel Co) in Shanghai, China.
Since its launch in 2013, WinGD’s X-DF engine series has gained a leading position in the low-pressure two-stroke dual-fuel market with over 1.5m running hours to-date. Building on the maturity of the original X-DF engine series, the second-generation X-DF2.0 platform was launched in 2020, with ambitious GHG reduction targets in mind. Since that time, more than 60 engines have already been ordered signalling the industry’s strong commitment to the energy transition.
WinGD’s Intelligent Control by Exhaust Recycling (iCER) became the first technology to be introduced to the X-DF2.0 series to reduce fuel consumption and cut methane emissions. iCER further reduces methane slip by 50% compared to the already low level of the first generation X-DF and lowers fuel consumption in both diesel and gas mode. The technology enables Tier III NOX compliance in liquid fuel mode without the need of additional SCR technology.
The company says that the uptake of the X-DF2.0 technology is rapidly expanding. With the latest optimised engine tuning, the results attained for the X-DF2.0 engine platform is believed to position it well for future-ready two-stroke technologym being retrofittable for future fuels.
The first delivery of the X-DF2.0 is due to be in operation in 2023 onboard two newbuild pure car and truck carriers (PCTC) running on LNG as fuel.
Volkmar Galke, Director Sales, WinGD said; “We always knew that our X-DF technology offers the greatest optimisation potential for operators looking to reduce emissions. However, ongoing test results are proof of engine concept beyond expectations which we believe puts our X-DF2.0 portfolio and holistic energy management solutions at the forefront of shipping’s energy transition.”
