PROPULSION UPDATE www.marinelink.com MN53Designed primarily for coastal work boats, RIB?s, power boats and sailing yachts, the Revolve marinized 5 cylin- der diesel engine has been developed from the renowned Ford Duratorq TDCi engine. Also playing a key role in the development of the engine?s cooling system was heat exchanger specialist EJ Bowman. As a result, the Revolve engine combines OE stan- dard engineering, packaging, product quality and heat management in acompact, space efficient unit. Alongthe way, Revolve was able to produce components that have taken marine engine cooling design to a new level. Working in partnership with Ford, the jointly developed technology for this engine has also been used inFord?s European model range, includ- ing the flagship Ford GT super car program. Arguably, and until now, marine engine technology has laggedbehind the automotive industry and hasn?t benefited from the technologi- cal leaps that have occurred ashore. That said; environmental issues that have been the focus of automotive engineers for decades are now being transferred to the marine industry; especially in terms of CO2 emissionsand noise. The new diesel engine from Revolve is a perfect example of an efficient response to that metric. Economy ? and Performance, too As the cost of fuel continues toclimb, boat operators find themselves concerned with not only the environ- ment, but how to survive in an increasingly expensive operational arena. In this case, the Revolve engine has been RCD certified for marine applications and offers power outputs of between 74 ?147 kW at the crank- shaft and is capable of cruising fully laden at about 40 knots. Delivering power with a high torque curve, which suits marine applications well, the engine?s remarkable fuel efficiency is also gratifying operators and theenvironment alike. In tests, it has reg- ularly achieved economic fuel con- sumption rates of 11 liters per hour, including high speed runs. This, cou- pled with the new engine?s low noise levels, could translate into greater range of ?stealth? military operations for the new entry in the small engine market. Reliable & Clean, too According to Revolve, and through- out the engine?s development, relia- bility has been a hallmark of this unit. Available now as 3.2 litre model, this five cylinder engine will later, it will be joined by a smaller four cylinder 2.2 litre version. In terms of emis- sions, the engine is fully Euro V emis- sions rated/compliant. Revolve backs those claims with a full 2 year/1,000 hours warranty, believed to be the first time a marine engine has ever been offered with this level of confi- dence.http://www.revolve.co.uk Revolve Tech partners with EJ Bowman to develop a new marine diesel engine.
