First 40cm bore electronic engine in service

摘要

Man diesel's first S40ME-B electronic engine has now entered service. Yielding 6810kW at 146rev/min and an mep of 21 bar, the new engine was built by STX in Korea and is one of six ordered by Inter-ship Navigation of Cyprus to power a series of vessels.rnThe ME-B engine is the prime mover aboard the Pacific Adventure, a multi-purpose vessel built at HuangHai shipyard in China. The newbuild-ing recently passed its sea-trials successfully.rnThe 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.
