MAN Diesel & Turbo and the Tier-III Age
The introduction of the electronically controlled camshaft-less low speed diesel engines (ME-range) are a milestone in diesel technology, a milestone that deserves a place in history similar to Rudolf Diesel’s first engine in Augsburg for the 1912 motor vessel Selandia, the introduction of turbocharging on two-stroke diesels in 1954, and the first SCR (Selective Catalytic NOx Reduction) systems on ships in 1989. The IMO Tier III NOx regulations that will come into force in 2016…
ClassNK Verifies NOx Emissions for Tier III Engine
ClassNK Issues First Ever Statement of Fact for Tier III NOx Emissions for an SCR-equipped Diesel Engine. ClassNK announced today that it had awarded its first ever Statement of Fact for Tier III nitrogen oxide (NOx) reductions to a marine diesel engine incorporating a Selective Catalytic Reduction (SCR) system. The document, issued on 1 November 2011, verifies that the NOx emission measurement results for the engine, fitted with a pre-turbocharger SCR system developed by Hitachi Zosen Corporation…

First Order Received For ME Engine in Japan
Hitachi Zosen Corp. has received an order for a Hitachi-MAN B&W ME engine. The order, for a 6S50ME-C,was placed by shipowner Nissho Shipping Co. Ltd., and is the first ME engine ordered in Japan. The shipbuilder is Naikai Zosen and the ME engine will be delivered in February 2004. The ME engine will be manufactured by Hitachi Zosen Diesel and Engineering Co., Ltd. Koike), based on a license agreement with MAN B&W Diesel A/S in Denmark. MAN B&W began the development of electronically controlled engines in 1987, and in 1991 it started an electronic control project for developing “Intelligent Engines”. Meanwhile, Hitachi Zosen commenced basic research on hydraulic pressure-driven fuel oil pressure boosting devices and exhaust gas valve control, without the use of a camshaft, around 1985.
