Federal-Mogul unveils piston skirt coatings

Federal-Mogul Powertrain has introduced two piston skirt coatings - EcoTough-New Generation (for gasoline engines) and EcoTough-D (for diesel propulsion units).

Federal-Mogul Powertrain has introduced two piston skirt coatings – EcoTough-New Generation (for gasoline engines) and EcoTough-D (for diesel propulsion units).

Building on previous EcoTough coatings, the US supplier says the new formulations reduce engine friction, wear and noise while dealing with the increasingly challenging loads and temperatures that exist in downsized, turbocharged engines. 

“Reducing frictional losses by applying materials expertise is a critical element of Federal-Mogul Powertrain’s work with engine manufacturers,” said Federal-Mogul Powertrain chief technology officer, Gian Maria Olivetti.

“Our new EcoTough piston skirt coatings have the increased durability necessary to perform for the life of the piston under the greater thermal and mechanical loads created by the latest generation of efficient engines.”

Gasoline and diesel engines require alternative solutions because of important differences in their relative combustion loads, piston geometry and the lubricity of their respective fuels.

Federal-Mogul Powertrain has accommodated these differences by formulating specific coatings for either gasoline or diesel applications.
