摘要

Ships powered by a MAN B&W S70MC engine built between 1990 and 1999 will be required to have the engine upgraded to meet IMO Tier I NOx levels because an 'approved method) as defined in MARPOL, has now been developed by the engine-maker. Thomas Knudsen, senior VP Low-Speed, MAN Diesel & Turbo, said: "Our new approved methods require that owners running selected MAN B&W models retrofit these engines to meet Tier I IMO emission requirements. These retrofits, comprising the installation of modem, slide-type fuel valves, will significantly reduce exhaust emissions." MAN Diesel & Turbos' approved method project has developed retrofits for the large number of engines covered by the IMO legislation. The retrofits consist primarily of the replacement of engine fuel-injection valves with newly developed fuel-injection nozzles, as well as adjustment and certification of the engines.
