WinGD touts fuel economy of dual-fuel engine

8% savings in gas mode achieved during testing; first engine commissioned in 2023

WinGD said its X-DF2.0 engine technology has exceeded initial expectations in terms of fuel economy.

According to the company, optimized engine settings on WinGD’s second-generation X-DF2.0 dual-fuel engine platform resulted in fuel savings of up to 8% in gasoline mode and up to 6% in diesel in recent tests at CMD (CSSC -MES Diesel Co) in Shanghai, China.

Since its launch in 2013, WinGD’s X-DF engine series has become the world’s best-selling low-pressure two-stroke dual-fuel engine with over 1.5 million hours of operation to date. Building on the original X-DF engine series, the second-generation X-DF2.0 platform was launched in 2020, with ambitious greenhouse gas (GHG) reduction targets. Since then, more than 60 engines have already been ordered, signaling the industry’s strong commitment to the energy transition, WinGD said.

WinGD’s Intelligent Exhaust Gas Recirculation (iCER) control became the first technology to be introduced in the X-DF2.0 series to reduce fuel consumption and methane emissions. iCER further reduces methane slip by 50% compared to the first generation X-DF and reduces fuel consumption in diesel and gas mode. The technology also enables Tier III NOX compliance in liquid fuel mode without the need for additional NOx reduction Selective Catalytic Reduction (SCR) technology.

Adaptable to future fuels, the dual-fuel platform provides flexibility for the future.

The first delivery of the X-DF2.0 should be operational in 2023 on board two new car and truck transporters (PCTC) running on LNG as fuel. The project will showcase not only WinGD’s core engine development expertise, but also its in-depth knowledge of the optimization potential of integrated hybrid systems, a solution also developed and delivered to WinGD’s customers.

“We have always known that our X-DF technology offers the greatest potential for optimization for operators looking to reduce emissions,” said Volkmar Galke, Director of Sales at WinGD. “However, the results of ongoing testing are proof of concept for the engine beyond expectations, which we believe puts our X-DF2.0 portfolio and holistic power management solutions front and center. -care of the energy transition of maritime transport.”
