EcoTough Coated Diesel Pistons

Federal-Mogul Corporation has developed a coated diesel piston, known as the EcoTough Coated Diesel piston, that reduces frictional losses in both light- and heavy-duty engine applications.

• Improves fuel economy, CO2 emissions, noise and refinement
• Reduces friction by up to 13%, compared with conventional graphite coatings
• Features high wear resistance
• Wear resistance can be used in design process to increase piston skirt clearance, further reducing friction and fuel consumption without compromising NVH and engine durability
• Meets requirements of highly loaded diesel engines
• Uses solid lubricants, including graphite and a carbon fiber reinforced polymer base to provide lower friction, higher scuff resistance and improved wear resistance
• Delivers the specified thickness necessary to ensure increased skirt clearance allows no lateral movement of the piston, which would otherwise compromise NVH
• Compatible with existing and advanced cylinder bore finishes and can be introduced in volume engine production as a running change
• Meets the most stringent environmental standards and contains no toxic solvents
