It’s a novel concept but a new piston design from Federal-Mogul could help reduce fuel consumption and lower emissions.
The next generation of the Monosteel piston, known as the Magnum Monosteel, has a design that reduces mass by as much as seven per cent. It includes a double band piston skirt design that helps reduce frictional drag while also reducing the overall piston skirt area by a substantial 40 per cent. This means that the design feature is the primary contributor to Magnum’s overall friction and mass reduction. The design also ensures that there is better hydrodynamic lubrication which means greater piston stability and optimal ring pack performance and durability.
The new Magnum Monosteel piston.
Thanks to extensive engine testing, it has been shown that piston friction is reduced by 17 per cent compared to conventional steel piston designs.
Both the original Monosteel and the new Magnum Monosteel have also patented dual friction-welded construction. This allows large cooling galleries for superior high temperature resistance meaning it has the strength to withstand the high cylinder pressures that are usually found in modern commercial vehicle engines.
Now the Magnum Monosteel piston is being tested with major global commercial vehicle and engine manufacturers throughout Europe and North America.
