Sulzer is a long-established Swiss engineering company with a rich history, particularly known for its marine diesel engines. The company’s engine division was acquired by Wärtsilä in 1997, and as a result, Sulzer engines are now manufactured under the Wärtsilä-Sulzer brand.
The most widely used Sulzer engine series in the marine industry include:
Sulzer RTA Series (Including RT-flex)
The RTA (Reliable Turbocharged Diesel Engine) series is one of Sulzer’s most well-known and modern engine lines. It’s distinguished by its advanced turbocharging technology and fuel efficiency. This series includes several sub-models:
- RTA-C Series: High-power engines designed for container ships.
- RTA-T Series: Ideal for slower-moving vessels like tankers and bulk carriers.
- RT-flex Series: This is the electronically controlled version that uses Sulzer’s modern common-rail fuel injection system. It eliminates mechanical camshafts and fuel pumps, leading to lower fuel consumption, reduced emissions, and improved performance. The Wärtsilä-Sulzer RT-flex96C is one of the most famous models in this series and is known as one of the world’s most powerful diesel engines.
Sulzer RND and RND-M Series
While these series are older than the RTA series, they are still used on many vessels due to their robustness and reliability. The RND engines are known for their opposed-piston design instead of an exhaust valve, which reduces maintenance requirements.
Sulzer Z Series
The Z Series engines are medium-speed, four-stroke engines. Models like the Z40 and ZA40S have been used as both main propulsion engines and for generator sets. Their more compact design makes them a preferred choice for auxiliary machinery and smaller vessels.
Sulzer’s engine designation system typically follows this pattern:
- Letters: Indicate the main engine series (e.g., RTA, RND, ZA).
- First Number: Specifies the number of cylinders (e.g., 6RTA, 8RND).
- Second Number: Indicates the cylinder bore in centimeters (e.g., RTA96C, Z40).
- Final Letter: Designates the engine’s sub-type or feature (e.g., A-turbocharged, U-reversible, C-for container ships).
