Did you know
- The Wärtsilä Sulzer RT-flex96C is an electronically controlled common-rail version of the RTA96C engine series, which was introduced in 1994. The first 12-cylinder RT-flex96C successfully completed shop testing in June 2004, and the 14-cylinder variant, the largest in the series, entered commercial service in September 2006 aboard the *Emma Mærsk*.
- The RT-flex96C is part of Wärtsilä Sulzer's low-speed, two-stroke engine family, designed for large marine propulsion. It is an advanced iteration of the RTA96C, incorporating common-rail technology.
- This model is chosen for its ability to provide high power output for ultra-large container ships, combined with improved fuel efficiency and reduced emissions due to its electronically controlled common-rail system. The common-rail technology allows for precise fuel injection and valve actuation, leading to smokeless operation at all speeds and better performance at lower RPMs.
