A testing programme with factory personnel commenced in January 20111 on a 6S46MC-C8 engine built by licensee Hitachi Zosen: the purpose was to commission the engine control system and optimize the integration of the SCR equipment. The engine develops about 7 MW at a speed of up to 129 rpm. The SCR removes NOx from the exhaust using urea as an activator. Further reduction of emissions in the exhaust system are achieved using Exhaust Gas Recirculation (EGR) techniques. On completion of the tests, MAN Diesel & Turbo claimed a world first as the engine met all emission requirements laid down in the IMO Tier 3 regulations effective 2016. [More]
