Full engine portfolio to meet IMO Tier-II limits

MAN Diesel’s Environmental Milestone

2 June, 2008. MAN Diesel is relaunching its portfolio, making all its engines compatible with the limits established by the International Maritime Organisation (IMO) in its Tier II regulations. The relaunch is an historic milestone for the company, and one which preempts the January 2011 implementation of the new IMO NOx emission limits by some time.

The new programme was launched this very week at Asia Licence Days, a meeting of MAN Diesel licensees in Okayama, Japan. 160 participants, including the top management from MAN Diesel’s two- and four-stroke licence family in Japan, China, Korea and Vietnam, met to discuss the new implications for MAN Diesel’s product portfolio.

Executive Vice President of MAN Diesel, Peter Sunn Pedersen, comments: “During this summit, we have updated our Asian family of licensees on the latest developments with particular emphasis on environmental issues and given our view on diesel technology in this regard today and in the future. Therefore technological challenges with the main focus, of course, on environmental challenges such as cutting emissions and the application of bio-fuels, etc. was discussed in detail. He concludes: “What we are doing is a complete optimisation of the engine-installation, whether electronically or mechanically controlled.”

Locating the venue in Asia is an expression of how important this market is to MAN Diesel. This is required by the many newbuilding orders currently placed at Asian yards, many of which are due for delivery in the wake of Tier II implementation.

“It is a milestone – we have been working on this for many years,” says Peter Sunn Pedersen. “You can divide the changes into two groups. With the electronically-controlled engines we have focused on advanced rate shaping, a unique feature of our ME system of the injection process, while on the conventional engine types we have adjusted combustion through design.”

Having addressed Tier II, MAN Diesel will next turn its focus to the Tier III regulations, successor to Tier II and due to come into force in a decade.
