Sulzer Engines Nomenclature: Its Important Guys!

SULZER ENGINE NOMENCLATURE:OFFICIAL BY WARTSILA CORP

Special Thanks to Mr Wasim Hussain N of MEO Class IV Preparatory Group on Facebook for sharing this essential information!
This guide is not considering the engine nomenclature which existed prior to 1960s. As those engines are nearly extinct by now.

As per SULZER ENGINE WARTSILA CORP, they have categorized their engines into three main categories in the period of 1960s-1990s, where,

• 'R' : Low Speed Engines
• 'Z' : Medium Speed Engines
• 'A' : High Speed Engines

Further, talking about 'R',

'R' is universal Wartsila identifier for LOW SPEED-TWO STROKE Engine Family.

They cover engine typesRSD to RT-Flex.

Also RTA 'Super long Stroke' 6RTA58 (1982) is covered in it.

RT-Flex 58T-B was fitted with common rail system and exhaust valve full electronic control system.

Talking about other letters,

'C' : Container Ship Engine

'D' : Identifier for Reversible Marine Propulsion Engine (eg. RD, RND)

'E' : Electronic Transmission

'F' : Identifier for non reversing marine engine

'G' : Dual Fuel Type Engine, good for Gas also

'L' : Long Stroke Marine Engine

'S' : Super Long Stroke Marine Engine

'SS' : Marine Auxiliary Engine

'T' : Turbocharged

'A' : Revised Version

When I did a deep research, I have found out that any of the engine manufacturer doesn't really have a proper full form of any of their engine names. They kept of innovating and the series of the names kept of changing.
But the above report is on a conclusion offered by one of the Wartsila Corp!

Thank You for reading!
