Draft:WinGD - Winterthur Gas & Diesel

WinGD, or Winterthur Gas and Diesel Ltd., is an engineering research and development company located in Winterthur, Switzerland. They design two-stroke engines for deep-sea merchant ships. The company originated from the diesel engine business of Sulzer Corporation, established in 1893 when the Sulzer Brothers signed an agreement with Rudolf Diesel for his new engine technology.

Sulzer started diesel engine manufacturing in 1903 in Winterthur. In 1986 the last diesel engine left the Winterthur facility.

Going forward to November 1990, Sulzer established its Diesel Engine & Diesel Power Plant Division as a separate company, New Sulzer Diesel Ltd.

In April 1997, New Sulzer Diesel Ltd. merged with Wärtsilä Diesel Oy to create Wärtsilä NSD Corporation which later became Wärtsilä Corporation. The Swiss company, Wärtsilä Switzerland Ltd., responsible for the low-speed, two-stroke engine within Wärtsilä, was merged with China State Shipbuilding Corporation (CSSC) in early 2015 and renamed Winterthur Gas & Diesel Ltd. (WinGD). In 2016, Wärtsilä Corporation transferred its remaining shares of WinGD to CSSC making WinGD 100% owned by CSSC.

The engine brand was changed from 'Wärtsilä' to ‘WinGD’. Today WinGD supports its engines with hybrid energy management, digital technologies, training and warranty services.
