WinGD · X-SERIES · RT-flex · X-DF
Genuine, OEM and reconditioned spares for WinGD low-speed two-stroke engines — X-series, the inherited RT-flex common-rail range & X-DF dual-fuel — sourced beside Alang, shipped to India, UAE, Singapore & worldwide.
A TWO-STROKE LINEAGE
The low-speed two-stroke story begins in Winterthur with Sulzer Brothers — the foundation that WinGD still carries forward today.
Wärtsilä absorbs Sulzer’s marine diesel business, taking the RTA platform and the new common-rail programme under its name.
The RT-flex series brings electronically-controlled common-rail injection and exhaust-valve actuation — later inherited by WinGD.
The low-speed engine business is spun off as Winterthur Gas & Diesel (WinGD), an independent maker carrying the Sulzer/Wärtsilä lineage.
WinGD’s X-series and low-pressure X-DF dual-fuel engines lead the move to LNG, methanol and ammonia-ready propulsion.
WHO IS WinGD
WinGD — Winterthur Gas & Diesel — is the maker of the low-speed two-stroke engines that drive the world’s largest merchant ships. It is the direct successor to the Wärtsilä and Sulzer two-stroke business, spun off as an independent company in 2015. Because the RT-flex common-rail range carried over from Wärtsilä, a single engine room may hold an RT-flex unit alongside a current WinGD X-series or X-DF dual-fuel block. Wattmare supplies spare parts across the full WinGD line-up — X-series, RT-flex and X-DF.

GLOSSARY
WHERE WE DELIVER
We ship WinGD parts from Alang / Bhavnagar to UAE, Dubai, Singapore, Greece, Turkey & worldwide in 24–48 hours.
Wattmare is a specialist WinGD engine spare parts supplier serving India, the UAE, Singapore and the wider global fleet. From our base in Bhavnagar — beside the Alang ship-recycling yard — we supply genuine, OEM-equivalent and reconditioned spares for every WinGD (Winterthur Gas & Diesel) marine two-stroke engine. Whether you run a current X-series block, an inherited RT-flex common-rail engine or an X-DF dual-fuel unit, we hold the wear parts, injection equipment and running gear you need and dispatch them worldwide in 24–48 hours.
WinGD’s low-speed engines trace back through Wärtsilä and Sulzer. The two-stroke business was spun off as an independent company, Winterthur Gas & Diesel, in 2015. In practice this means the parts market spans three names. The X-series (X35-B, X40-B, X52, X62, X72, X82, X92) is WinGD’s flagship current range. The RT-flex series (RT-flex50, RT-flex58, RT-flex60C, RT-flex68, RT-flex82C, RT-flex96C) introduced common-rail electronic injection under Wärtsilä and carried over to WinGD. And the X-DF dual-fuel engines lead the industry’s shift to LNG. We supply spares across all of them.
WinGD’s X-DF is a low-pressure dual-fuel platform that burns LNG on the Otto cycle with a small pilot fuel injection. Later developments — X-DF2.0 with iCER, and the X-DF-A ammonia and X-DF-M methanol programmes — position WinGD at the centre of marine decarbonisation. We source gas admission valves, pilot fuel equipment, running gear and combustion parts for the X-DF range, genuine and reconditioned.
For class-critical or newbuild work, genuine WinGD parts are the safe choice. For routine planned maintenance, OEM-equivalent aftermarket parts cut cost by 30–50%. And for emergency repairs or budget overhauls, reconditioned parts recovered from Alang, inspected and certified to OEM tolerance, can save up to 70%. Every reconditioned part ships with an inspection report, dimensional measurements, photographs and a 30-day warranty.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including container ships and bulk carriers running WinGD and inherited RT-flex engines. That gives Wattmare direct access to genuine, low-hour parts that are otherwise slow and costly to source from distributors, at a fraction of new-part lead time. Browse our reconditioned marine spare parts range, the wider main engine spare parts category, or sister brands like Sulzer and Mitsubishi UEC.
