论文已在上海2013年CIMAC大会上发表，论文版权归CIMAC所有。 The IMO Tier ll NOx regulations will come into force in 2016. This means that NO, emissions from large two-stroke diesel engines must not exceed a cycle value of 3.4 g/kWh, and NOx emissions must not exceed 5.1 g/kWh on the individual load points of the load cycle. To comply with the Tier Ill requirements, MAN Diesel & Turbo(MDT) is involved in a targeted and continuous development of exhaust gas recirculation(EGR) for NOx reduction on low speed two-stroke diesel engines. The latest investigations on MAN Diesel and Turbo's research engine in Copenhagen regarding the next generation of EGR system, scrubber performance, high speed and high efficiency EGR blower and water treatment system will be covered. The following topics will be described: confirmation test of integrated EGR system design, sulphur and particle reduction ratios in the EGR scrubber, blower performance and water treatment system functionality and requirements. The first MAN B&W Tier ll EGR diesel engine has been successfully delivered for a 4,500 teu container vessel. The following topics regarding the first Tier IIl EGR two-stroke diesel engine will be covered: engine integrated design with multiple turbochargers, EGR auxiliary equipment, installation aspects and shop test performance results. The development process of the 6S80ME-C9.2 EGR engine has resulted in a finalised EGR engine design, and implementation on other engine sizes is in progress.
