Germany: MAN Diesel's first S40ME-B electronic engine has entered service. Yielding 6,810kW at 146rpm and a mep of 21 bar, the new engine was built by STX in Korea and is one of six ordered by Intership Navigation of Cyprus to power a series of vessels.
The ME-B engine is the prime mover aboard the 'Pacific Adventure', a multi-purpose vessel built at HuangHai shipyard in China. The newbuilding recently passed its sea-trials successfully.
The market requirement for the lowest possible propeller speed in relation to bore size has led to the new ME-B engine having a stroke/bore ratio of 4.4. In turn, the new engine has an increased maximum cylinder pressure, giving rise to an improved fuel consumption that is 2g/kWh lower than existing, small-bore engines. Thanks to the electronic control of the engine's parameters, the ME-B is also well-equipped to meet the new Tier-II emission requirements.
"Market reception for the ME-B series has been very positive to date and, with over 100 orders recorded thus far," said Ole Grøne, Senior Vice President, MAN Diesel Promotion and Sales.
MAN Diesel introduced the ME-B concept in mid-2006 with the small-bore S35ME-B and S40ME-B MAN B&W engine designs. It subsequently expanded the series in early 2007 with the launch of the S50ME-B MAN B&W engine design, with the result that the entire ME-B programme now comprises a total output range from 2,975kW to 16,020kW.
The economical ME-B design utilises a camshaft-operated exhaust valve and an electronically controlled fuel injection system. This fuel injection makes the new ME-B engines particularly well equipped to meet Tier II 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 ME-B engines, ensuring a very low, cylinder lubricating-oil consumption.
The ME-B range now offers 35-, 40-, 46-, 50- and 60-cm models in the smaller bore range, while MAN Diesel's ME-C concept covers the medium- to large-bore segment of the market.
