Another current solution generating electrical power via a generator driven by a two-stroke diesel or dual fuel engine, is the constant frequency (CF) unit, which is located at the front end of the main engine. This serves to drive an​​ alternator, whereby the generator speed, despite the varying speed of the main engine, is held constant through a planetary, hydrostatic transmission. A torsionally soft connection of the RCF generator unit to the main engine is advantageous here in terms of better torsional vibration behavior. Hereby, it is possible for the generator unit to continue to be run safely during misfiring of the main engine. The highly flexible coupling VULKAN RATO S or RATO S+ fulfils these criteria very well.
