Sulzer RT-flex. Conclusion\r\n
Common rail is now an industrial standard for diesel engines. It has been proven to be an tremendous step forward for all sizes of diesel engines from automotive engines up to the largest low-speed two-stroke engines.
In this environment, Sulzer RT-flex engines have become well accepted by shipowners. Shipowners’ confidence is being encouraged by the good operating experience with the growing number of RT-flex engines in service.
The combination of common-rail concepts and fully-integrated electronic control applied in Sulzer RT-flex engines clearly has excellent potential for future development. It gives the large degree of flexibility in engine setting and operation, together with reliability and safety, which are required to meet the challenges in future marine engine applications in terms of emissions control, optimised fuel consumption, insensitivity of fuel quality, ease of use, operational flexibility, etc.
Fig 12. The world’s most powerful common-rail engine, the Sulzer 12RT-flex96C engine develops 68,640 kW at 102 rpm, and measures about 24 m long by 13.5 m high. It passed its official shop test in June 2004. The supply unit can be seen at the middle of the engine.
