WinGD Two-Stroke DF / LNG Technology Update - Konrad Räss

Power Range for WinGDX-Engines(Diesel)


Power Range for WinGDX-DF Engines(Dual-Fuel)

Technology UpdatesCombustion chamber components


Optimized liner wall temperatures– Cooling bore

insulation for low ratings

– Mid-stroke insulation– Shorter water

guide jacket– Adapted water cooling

Pulse Lubricating System+ grooves

Liner plateauhoned

Anti-polishing ring

2 piston rings for 52,62,723 piston rings for 35,40,82,92– Top ring gas-tight– Cr-ceramic coated, all rings

since 2006!– Pre-profiledPiston ring grooves withthick chromium layer

Piston skirt nitro carburized

Technology UpdatesCylinder lubricant distribution principle, key for reliability


– The Pulse Jet cyl. lubricating system in combination with patented lubricating oil grooves plus updated pump and nozzle design results in an excellent oil distribution

– Large list of validated cylinder oils support user to select the correct oil and to optimise the feed rates

– Very low wear rates of cylinder liners and piston rings

– It has been clearly demonstrated that WinGD’s tribology concept and engine design is well suited to the operating conditions expected into 2020 and beyond (0 up to 3.5% and higher sulphur fuels)

– Feed rate optimised according to scrape down oil analysis for residual BN and total iron

X-DF Service Feedback

X52, MV S, 5054hrs

₋ Excellent piston running behaviour

₋ Inspection done in 2019, fuel S% between 0.36 –1.7% S, BN 100 mostly, for the 0.36% S fuel BN < 25


Liner wear >0.01mm/1000h

X52DF, MV EB, 1848hrs, 25BN oil


₋ Excellent piston running behaviour₋ Very clean components₋ No sign of blow by along the piston ring

Cylinder liner conditions after21’000 hrs on first X62DF


– Excellent piston running behaviour

– Wear rates close to zero

– No corrosion is needed with our tribology concept to achieve long TBO

Liner wear >>0.01mm/1000h

12X92DF, Impressions after FAT and Seatrial

₋ Excellent piston running component behaviour

₋ Piston rings with perfect running in wear pattern

₋ Inspection after sea trial was carried out after a longer manoeuvring on diesel, therefore the black oil

₋ Same Unit, same hours (+-2’500hrs) –

₋ ECA fuel₋ Same trade route₋ Same BN and feed

rate₋ Low detergency vs

improved detergency

WinGD Lubricants Guideline

20 © 2020 WinGD

Find the guide at wingd.com Search Validated Cylinder Oils to see the latest version

₋ New oil list with detailed usage guideline for each product introduced beginning of June 2020

₋ Not every oil from the same BN category has the same usage guideline to consider the different formulations (e.g. detergency, thermal stability, etc.) and the results of the field tests performed.

₋ New list very transparent and customer friendly. The customer can better compare the oils and the usage differences are clearly visible. This will also push the oil companies to develop better products to be competitive on the premium segment. Additionally, it justifies the price differences for the premium products which was previously not obvious.


WinGD Lubricants Guideline


Operation of WinGD Engines with VLSFO and LNG

23 © 2020 WinGD

Conclusions₋ Use of VLSFO did not lead to an increased number of damage reports.

₋ Our tribology concept works for all fuels from LNG to 3.5 % S.

₋ WinGD considers lubricant oil as a design element of that engine itself. The correct lubricant is key for reliable engine operation.

₋ WinGD works together with the oil companies to develop cylinder oils with higher cleaning ability.

₋ The latest lubricant guideline gives a more transparent insight of how products were tested.

₋ No component changes are required for 2020 compliant fuels.
