MAN Diesel & Turbo has added three new engines to its programme of ultra-large engines, intended for, among other types of vessels, ultra-large container vessels (ULCVs) and feeder vessels. The engines are of optimized weight, in comparison to their Mk 9 siblings, and represent a new design for the Mk 10 platform of the portfolio. The key feature of the new platform is the development of the top controlled exhaust valve and the booster valve (the fuel booster injection valve component). The new units are: MAN type B & W G90ME-C10, 6,240 kW per cylinder; MAN type B & W S60ME-C10, 2,490 kW per cylinder; MAN type B & W S70ME-C10, 3,430 kW per cylinder. This is the first time that the fuel booster injection valve has been used for such a purpose. It was a pilot project installed on a container ship only six months before it was placed on the market.
