摘要

Wartsila reports that its first upgraded RT-flex68-D engine equipped with a VTG turbocharger has been successfully tested at Doosan in Korea and found to be fully compliant with IMO Tier II regulations.The main objective of the upgrade was to give the engine a slimmer outline to suit installation requirements for new-generation container ships with fine afterbody lines. This is achieved primarily by introducing a simplified supply unit and a new design for the scavenge air receiver, as well as RT-flex components. The addition of a variable turbine geometry (VTG) turbocharger provides extended flexibility over a broader load range, again in line with current container ship operating requirements. Further benefits resulting from the design change are simpler manufacturing and improved maintenance, with a greater commonality of parts with other engine types.
