HERCULES Project Raised the Bar for Perfomance of Piston Rings, Liners

Large bore diesel engine piston ring and cylinder liner design was ratcheted up more than a few notches on the efficiency scale by research that flowed from the (now concluded) European Union sponsored HERCULES project. The piston ring itself might seem a fairly inconsequential part of the whole engine, yet commercially important length of Time Between Overhauls (TBO)  is largely determined by piston running behaviour and its effects on the wear of piston rings and cylinder liners. Recognising this fact, one sector of the interrelated study was devoted to an investigation into how engine friction might be reduced, but first it may be helpful to reprise HERCULES.The HERCULES Project The project title word HERCULES is itself an acronym (at a far stretch) signifying ‘High Efficiency R&D on Combustion with Ultra-low Emissions for Ships’, which pithily defines the scope of the three-and-a-half year project led by MAN Diesel SE and Wärtsilä Corporation with a t...

HERCULES Project Continues

The HERCULES Project is a large scale cooperative project on marine engine R&D concerning sustainable and safe energy production from marine engines. It is supported by the European Commission and the Swiss Federal Government. Comprising a consortium of 43 partners, it is led by the major engine maker groups MAN Diesel & Turbo and Wärtsilä. The research program started up in 2004 covering the broad remit topics of higher efficiency, reduced emissions and increase reliability. So successful was the project that it was decided to continue the research program now known as Hercules-A with a new four year Hercules-B program to run in the period 2008 to 2011. It has been decided to continue the research cooperation by commissioning a part three program to be known as Hercules-C, planned to run over a three year period 2012 to 2015. [More]
