1.Wärtsilä -(Sulzer) Marine Diesel Engines Manufactures:
From 1879 to date, Sulzer is one of the largest manufactures of marine diesel engines used for the main propulsion for merchant ships of both four stroke and two stroke design. Sulzer has its own history. Rudolf Diesel as a young engineer followed up his studies by working as an unpaid workshop trainee at Sulzer Brothers in Winterthur, Switzerland.
Sulzer built its first marine diesel engine in 1898. In 1950 the company built its first two stroke marine diesel engine that was directly reversible, and five years later it introduced valve-less two stroke engines after-charging systems and spray cooled pistons. In 1954, it introduced the concept of turbocharging in its engines.
In later years it manufactured different series of marine diesel engines, namely the RD, RND, RND-M, RLA and RLB series. In 1981, in a change from the traditional manufacturing of marine diesel engines, Sulzer introduced a more efficient system of scavenging called “uni-flow scavenging."
As the latest models of two stroke marine diesel engine use uni-flow scavenging, the constant pressure turbocharged RTA series with a single poppet exhaust valve was developed. Later the new Sulzer diesel became part of the Wärtsilä Corporation, and the more advance automated engine of Wartsila is the RT-flex series.
From the Wärtsilä Corporation now you can get a wide range of marine diesel engines with different specifications.
