Engine manufacturer WinGD has upgraded its X-DF2.0 engine with iCER for liquid fuel
The company said this will reduce the ship’s capex and simplify engineroom layout while achieving Tier III emissions requirements in diesel mode.
Introduced in 2020, the second-generation X-DF 2.0 engine uses the company’s intelligent control exhaust recycling (iCER) technology to capture unburnt fuel (methane) before it is ejected through the exhaust, providing the engine a second chance to combust it.
The manufacturer said tests at WinGD’s laboratory engines showed that adaptations to the iCER technology extend Tier III NOx compliance to liquid mode as well, adding to its original use of reducing methane emissions and decreasing the fuel consumption in both gas and diesel operation.
WinGD said “This further adds to the long-term flexibility of the X-DF platform which blends the benefits of both the Otto and Diesel cycles into one engine platform without the need of additional SCR NOx reduction technology.”
The company has seen a steady increase in demand for its X-DF2.0 technology, especially in the LNG carrier segment and the company hopes the upgrade to the iCER technology will make the application of an SCR obsolete.
Given the mounting regulatory pressure and demand for cost-effective, compliant technology, WinGD said the upgrade provides a way to slash methane emissions while providing increased efficiency in gas and diesel mode.
The first engine delivery with iCER for gas and diesel mode, starting with X72DF series, is targeted for September 2022.
