Wabtec's Power Play
With shipowners pressed to upgrade machinery to meet strict new emission targets, there’s much confusion with chatter surrounding ‘decarbonization’ and ‘future fuels’, solutions that don’t exist today – and may not exist in mass for another generation – cluttering the conversation. Enter Wabtec, formerly GE Transportation, which today offers a Tier 4 compliant engine with no need for urea. Is it the cheapest propulsion solution on the market? No. But the Pennsylvania-based engine builder mounts a compelling case for its 250MDC diesel engine based on performance…
MerCruiser Big Block
Mercury MerCruiser has developed the next generation of big-block marine power – a new engine that produces more power and has better mid-range acceleration, lower emissions and superior fuel efficiency. Mercury MerCruiser engineers in Stillwater, Okla. – drawing on the expertise of the development teams at Mercury Racing – conceived, designed and engineered the new engine with support from Mercury engineers in Fond du Lac, Wis. The next-generation, naturally aspirated big block features high-performance aluminum cylinder heads that improve mid-range acceleration and increase power. High-octane fuel is not required – the engine runs on 87 octane and achieves remarkably low oil consumption.
A.P. Moller Orders 7K80ME-C9 Engine
MAN Diesel has received the first order for its 7K80ME-C, Mark-9 engine. Hyundai Heavy Industries (HHI) will build four engines for the A.P. Møller Group, intended for container ships to be constructed by the Korean Hanjin Group. The K80ME-C Mark-9 engine is extremely competitive in terms of production costs and cost per kW. The engine represents a comprehensive update of its Mark-6 predecessor with boosted power and adopts a number of design features also shared by the S65ME-C engine. a lighter design than its mechanical counterpart. Pressure is set at 20 bar, with maximum firing pressure at 160 bar. At 104 r/min and a mean piston speed of 9 m/s, the K80ME-C9 yields a power per cylinder of 4,530 kW/cyl.
Oil Consumption of Medium Speed Diesel Engines
Reliability and availability are of paramount importance to all users of internal combustion engines. Inherent engine design reliability must be complemented by a suitable periphery and the appropriate choice and treatment of working media such as lubricants and fuel. CIMAC Working Groups have a long tradition of preparing recommendations and guidelines for the internal combustion engine industry and its users. In performing this work, CIMAC takes advantage of its wide and competent international membership; Working Group -"Lubricant" is truly worldwide, with active members from Japan, U.S. and all round Europe/Scandinavia.
