| 1893 |
Headquartered in Switzerland, powering merchant shipping since 1893. |
| 1905 |
In 1905 the first reversing two-stroke marine engine was developed by Sulzer. |
| 1910 |
It led the way to the first valve-less two-stroke engines at sea, two 559 kW Sulzer 4SNo.6a engines in the Italian cargo ship ‘Romagna’ in 1910. |
| 1912 |
In 1912 the first ocean-going ship with valve-less crosshead type two-stroke engines was the German cargo ship ‘Monte Penedo’, which was equipped with two Sulzer 4SNo.9a engines with a total of 1250 kW. |
| 1930 |
Airless fuel injection became standard from 1930 in all engine types, greatly improving their efficiency and reducing their maintenance requirements. |
| 1946 |
The first turbocharged two-stroke diesel engine in normal operation was a Sulzer 6TAD48 engine in 1946 in the power house of the Winterthur facility. |
| 1950 |
Turbocharging became standard in marine low-speed engines for ship propulsion, which opened the chapter of the long series of Sulzer R-type low -speed engines – the RSAD, RD, RND, RND-M and RL types. |
| 1972 |
The first low-speed marine engine in the world running on gas entered service in 1972. The Sulzer 7RNMD90 engine was running on natural gas in the Norwegian 29,000m3 LNG carrier Venator. |
| 1981 |
In 1981 tests with electronically-controlled fuel injection began on a four-cylinder research engine. |
| 1983 |
A radical change in scavenging from loop to uniflow was made in 1983 with the introduction of the RTA low-speed engines of 380 to 840 mm cylinder bore, increasing to 960 mm in 1994. |
| 1986 |
The last engine manufactured locally left the Winterthur facility in 1986, after which all manufacturing moved to global operations in key locations throughout Asia, where the majority of ship building operations take place today. |
| 1994 |
In 1994 the cylinder bore of the RTA low-speed engines increased to 960 mm. |
| 1998 |
In 1998 the world’s first large, electronically-controlled low-speed engine with common-rail injection was introduced and running in the Diesel Technology Centre in Oberwinterthur, Switzerland leading to the launch of the RT-flex commonrail system. |
| 2001-09 |
The first RT-flex engine entered service in September 2001. |
| 2006-09 |
The world’s largest Diesel engines are now the 14-cylinder RT-flex96C engines of 80,080 kW (108,920 bhp) of which the first entered service in September 2006. |
| 2011 |
Later in 2011 Generation X-Engines were introduced to the market, offering greater efficiency in terms of fuel consumption and emissions. |
| 2011-02 |
In February 2011 a project began to develop dual-fuel gas engine technology for low-speed engines as a solution for complying with the upcoming IMO Tier III NOX emission limits without additional exhaust after-treatment. |
| 2011-09-19 |
Only seven months later, on the 19th of September, the new technology was successfully demonstrated on a full-scale research engine at the Wärtsilä factory in Trieste, Italy. |
| 2012 |
In 2012 the large bore X92 engine was added to the Generation-X engine portfolio. |
| 2012 |
The X92 engine directly reduces the emission levels of carbon dioxide, making it easier for the shipyard to achieve a better Energy Efficiency Design Index (EEDI). |
| 2013 |
In 2013, WinGD introduced the X-DF engine series. Dual-fuel engines, using gas admitted at low pressure and ignited by a low volume of liquid pilot fuel was a breakthrough in the marine industry. The X-DF engines offer new marine standards with low-pressure gas technology. |
| 2016 |
The interest in WinGD comes through their parent company, China State Shipbuilding Company (CSSC), who acquired the former Sulzer division of the two-stroke engine design business from Wärtsilä Corporation in 2016. |
| 2019-01-24 |
WinGD (Winterthur Gas & Diesel Ltd.) was host to a group of esteemed delegates from the Chinese Ministry of Industry and Information Technology (MIIT) this week. The delegation added Winterthur to their itinerary as part of their visit to Zurich, Switzerland for meetings with the China-Switzerland Innovative Strategic Partnership in advance of the 49th World Economic Forum annual meeting in Davos. |
