The six cylinder two-stroke engine, with a maximum continuous output of 11,640 kW, will be installed on a 50,000-tonne tanker built by CSSC Chengxi Shipyard for Japanese owner Kumiai Senpaku. SCR is one of the most effective methods of reducing NOx emissions in line with IMO’s Tier III requirements. WinGD aims to make SCR available as a first step for single turbocharger applications of its diesel-burning X-series low-speed engines. The X52 engine with iSCR is the latest collaborative project between WinGD and China Shipbuilding Power Engineering Institute, both owned by China State Shipbuilding Corp’s CSSC Power Group.
