FDML Develops New Coated Piston To Reduce Fuel Consumption, CO2 Emissions

ABR Staff Writer Published 19 July 2010

Federal-Mogul Corporation (FDML), a global supplier of technologies that improve powertrain efficiency and enhance vehicle safety, has developed a new coated piston for gasoline engines that combines the properties of low wear and low friction in a single application.

The new EcoTough-coated piston offers wear resistance and reduces fuel consumption up to 0.8%, as well as reduced CO2 emissions, compared to conventional piston coatings.

The new piston is compatible with existing and advanced cylinder bore finishes and can be introduced seamlessly in volume engine production as a running change.

The key behind the EcoTough-coated piston technology is the composition of the coating, which is comprised of solid lubricants, including graphite, molybdenum disulfide (MoS2) and carbon fiber.

Rainer Jueckstock, senior vice president of Powertrain Energy at Federal-Mogul, said: EcoTough is a proven solution that will help OEMs meet the stringent regulatory requirements for their vehicles.
