MAN Diesel has enhanced its electronic, low-speed, ME-B engine programme with the launch of the MAN B&W S46- and S60ME-B type engines. These add to the existing MAN B&W S35ME-B and S40ME-B engines that were introduced in mid-2006, and the S50ME-B that was introduced in early 2007.

The ME-B design is based on the experience gathered from MAN Diesel’s existing engine ranges, among the most popular engines available on today’s market with a combined total of over 3,000 engines in service. The economical ME-B design utilises a camshaft-operated exhaust valve and an electronically controlled fuel-injection system. In addition, the physical dimensions of the S46- and S60ME-B bedplates are identical to those of their MC-C and ME-C equivalents, greatly facilitating installation of the new technology with the same footprint if required.
Electronic fuel injection makes the new ME-B engines well-equipped to meet the new Tier 2 emission requirements, and is an efficient way of managing current environmental-emission requirements.
As with the larger MAN B&W ME-engines, the Alpha Lubricator comes as standard with all engines, ensuring a very low, cylinder lubricating-oil consumption as the advanced, electronic, user-friendly interface allows precise adjustment.
Market reception for the ME-B series has been very positive to date with a significant 88 orders already received.
The first ME-B engine was built in December 2007 by STX Heavy Industries Co., Ltd. at its Changwon works in Korea. The 6S40ME-B delivers 6,810 kW at 146 rpm with an MEP of 21 bar and, on account of its excellent performance, MAN Diesel decided to extend the ME-B concept to the S46- and S60 segments.
With the launch of the new engines, the entire ME-B programme now boasts a total output range from 4,350 kW to 19,040.
Ole Grøne, Senior Vice President, MAN Diesel Promotion and Sales, commented: “The ME-B series has been an outstanding success since its inception and orders have exceeded even our own, optimistic expectations. The ME-B range fills a gap in the modern prime-mover market and, with the introduction of the S46- and S60ME-B units, MAN Diesel’s latest engine family now has an even broader appeal.”
In summary, the ME-B series offers optimal engine performance in powerful, economic and future-oriented diesel engines, ensuring that they will remain market leaders for decades to come. Based on well-proven diesel technology, the ME-B series provides engines geared to market requirements for: electronic fuel-injection control reliability longer time between overhauls better vessel manoeuvrability very low life-cycle costs.
