Swiss engine maker, Sulzer’s foray into two-stroke marine engines began in the early 20th century when Sulzer developed some of the world’s first large marine diesel engines. A major breakthrough came in the 1950s with the introduction of the RD series, followed by the highly successful RND and RTA engine families. These engines helped establish Sulzer as one of the leading suppliers of low-speed marine propulsion engines, powering everything from tankers and bulk carriers to container ships. Sulzer’s constant focus on fuel efficiency, reliability, and long-stroke engine design culminated in the launch of the RTA84C engine in 1988, which became one of the most widely used large-bore marine engines of its era. In 1990, its diesel engine division was separately set up as New Sulzer Diesel before being sold and merged into Wärtsilä NSD in 1997 and later into WinGD, completely owned by CSSC in 2016. The engine lineage continued through the electronically controlled RT-flex and modern X-series engines, which remain among the most efficient two-stroke marine engines in service today.

Although the production of two-stroke diesel engines with the Sulzer name on them has stopped, they are still going strong and powering many vessels around the world. And Alang Maritime is ready to supply parts for them to prolong the life of your Sulzer engines as much as possible.
