WinGD says that its new Intelligent Control by Exhaust Recycling (iCER) system is designed to ‘slash methane emissions and cut fuel consumption’ in its X-DF dual-fuel engines.
Announcing the new system, WinGD said: ‘The iCER system delivers enhanced combustion control through the use of inert gas. The result is a reduction in methane slip emissions of up to 50% when using LNG and a significant reduction of fuel consumption, of 3% in gas mode and 5% in diesel mode.’
Volkmar Galke, WinGD Global Director of Sales, commented: ‘By adjusting the recirculation rate of inert gas and controlling parameters like fuel admission and ignition timing, we can increase compression ratios for greater efficiency. The result is optimised combustion through closed-loop control regardless of ambient conditions and load.’
The iCER system, which will be available for all new X-DF engines, is currently completing trials at one of WinGD’s dedicated test engine facilities and the company is also finalising plans for a pilot installation.
Concerns over ‘methane slip’ have caused some to question LNG’s suitability as a ‘transition fuel’ that the shipping industry can use on its migration from traditional fossil fuels to future zero-emission alternatives such as hydrogen or ammonia
