Exhaust Gas

First Tier-III-Compliant, Two-Stroke Engine Unveiled in Japan

MAN Diesel & Turbo confirms that MAN B&W 6S46MC-C8 engine with integrated SCR fulfils the IMO’s strictest emission standards The engine, an MAN B&W 6S46MC-C8 type capable of an output of almost 7 MW, was constructed in autumn 2010 by Hitachi Zosen Corporation at its Ariake works in southern Japan. The engine is bound for a general cargo carrier, to be built at the Nakai shipyard and scheduled to enter active service later this year. The vessel was ordered by Japanese customer,  BOT Lease Co. Ltd., and is operated by Nissho Shipping Co. Ltd. The first engine-start took place in January 2011. In connection with this, MAN Diesel & Turbo dispatched a team to Japan to commission the engine-control system – the first in a series of planned visits. The team also optimised the integration of the SCR system that removes NOx from the engine’s exhaust gas. The SCR system features: *  more than 80% NOx reduction based on the load cycle *  more than 70% NOx reduction on each load point in the load cycle *  easy switching between on/off modes for optimal emission performance on high seas and coastal waters. Ultimately, MAN Diesel & Turbo confirmed  that, in a world-first, the engine meets all emission requirements as stipulated by the International Maritime Organisation’s Tier-III legislation, due to come into force in 2016.
