Sulzer RT-flex engines are the most advanced large two-stroke marine diesel engines today to have electronically-controlled common-rail systems for fuel injection and valve actuation. Common-rail is now an industrial standard for diesel engines of more or less all sizes. In this environment, Sulzer RT-Flex engines have become well accepted by shipowners, particularly in the largest cylinder size, the RT-flex96C. Shipowners' confidence is being encouraged by the good service experience with the growing number of RT-flex engines in service. With the successful testing of the Sulzer RT-flex96C engine, common-rail technology has been proven to be an excellent step forward for all sizes of diesel engines from automotive engines up to the largest low-speed two-stroke engines. For Sulzer RT-flex engines, a key virtue of common-rail systems has been that they can be modular with standardised hardware applicable to more than one engine bore size. The combination of common-rail concepts and fully-integrated electronic control applied in RT-flex engines has the best 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 to fuel quality, ease of use, operational flexibility etc. All RT-flex functions are governed by the WECS (Wärtsilä Engine Control System) which triggers the corresponding electro-hydraulic rail valves for the respective hydraulic functions. The master input comes from the crank angle sensor which delivers the absolute crank position. WECS communicates with the ship's machinery control system by an adapted version of DENIS (Diesel Engine Interface System).
