Reduction of Friction and Parasitic Losses of Large-bore Diesel Engines

During recent decades, the overall efficiency of two- and four-stroke large-bore diesel engines has been unmatched by any other engine application. However, smaller engine categories - like heavy-duty truck engines - achieved significant progress in both indicated and mechanical efficiency. To transfer this potential to medium-speed large-bore engines, private and public research institutes and an OEM formed the public funded eta-up project.
