Hybridization – new challenges for an efficient powertrain

Due to stricter requirements regarding environmental protection and NVH, hybrid drive concepts are increasingly being used in the marine industry. The change of system architecture and electrification pose new challenges for the powertrain. Furthermore, background noise, concealed under the operating noise of the diesel engine, will be clearly audible in the future. Hybridization topics such as system efficiency, low weight, electrical insulation as well as non-magnetic properties are making demands on the powertrain. Specially developed Geislinger acoustic coupling solutions offer the possibility of reducing vibrations and subsequently optimizing the NVH properties of the powertrain.
