The addition of iCER delivers a 50% discount of methane slip on X-DF engines working in fuel mode.
Winterthur, Switzerland, headquartered low-speed fuel and diesel engine developer WinGD has launched an on-engine model of its Intelligent Control by Exhaust Recycling (iCER) emissions discount system.
Designed to cut back methane slip emissions and lower gas consumption on WinGD’s extensively deployed X-DF dual-fuel engines, iCER is the primary X-DF 2.0 know-how launched to additional increase the emissions efficiency and effectivity of the X-DF two-stroke engine sequence. While X-DF engines working on LNG already provide a greater than 20% discount in greenhouse fuel emissions and a dramatic discount in air air pollution in comparison with gas oil, the addition of iCER delivers a 50% discount of methane slip in fuel mode. Combined with higher gas effectivity, this reduces whole greenhouse fuel emissions by as much as 8% in fuel mode. Running on diesel, iCER improves the emissions efficiency of X-DF engines by 6%.
The on-engine iCER gives the identical benefits whereas simplifying testing, constructing and set up of the engine, in addition to decreasing the engine room house wanted for emissions discount tools. The exhaust fuel cooler and all exhaust fuel movement management elements are put in on the engine, providing important engine room design flexibility.
“This important addition to the choices in our X-DF2.0 portfolio extends the benefits to all shipyards and global engine builders with an improved arrangement and a production-friendly design for minimiz
ed manufacturing and installation costs,” mentioned Dr. Rudolf Holtbecker, government director of operations at WinGD.
On-engine iCER is initially accessible on WinGD’s X72DF engines, which have develop into the usual on trendy LNG carriers. Minimizing methane slip on LNG carriers has an additional benefit for operators utilizing their cargo as gas, permitting them to maximise the worth of the LNG delivered. The know-how might be rolled out to different fashions within the X-DF engine vary.
The precept behind iCER is to reduce emissions by regulating air and exhaust fuel movement. By cooling and recirculating exhaust again to the engine, extra gases which may contribute to local weather change are combusted with out escaping into the ambiance.
As effectively as decreasing methane slip and whole greenhouse fuel emissions, each on- and off-engine iCER allow compliance with IMO’s Tier III NOx limits, whether or not utilizing LNG or diesel fuels.
