Did you know

The Wärtsilä Sulzer RTA50C was announced in March 2003 as a new low-speed marine diesel engine, developed jointly by Wärtsilä and Mitsubishi Heavy Industries Ltd.. The first engines of this type were expected to be completed towards the end of 2004.
The RTA50C is part of the broader Sulzer RTA series, which includes models with various bore sizes.. It is a conventional camshaft-based engine, serving as the foundation for the electronically-controlled common-rail RT-flex50C.
The RTA50C was designed to meet market needs for reliability, high efficiency, compactness, and environmental compliance, including NOx emission regulations.. It offers a traditional engine concept for shipowners who prefer it over electronically-controlled systems.
