EcoTough Piston Skirt Coatings

[Increase Durability for the Life of Pistons]

Federal-Mogul Powertrain has introduced two innovative piston skirt coatings, EcoTough-New Generation (for gasoline engines) and EcoTough-D (for diesel engines) that are claimed to reduce this friction by up to 15 percent compared to standard coatings.

Building on the proven performance of previous EcoTough coatings, the new formulations further reduce engine friction, wear and noise while dealing with the increasingly challenging loads and temperatures that exist in the latest downsized, turbocharged engines.

The coating is a metal oxide-reinforced resin with embedded solid lubricant particles and it’s applied in a thickness of 15 microns to the piston’s skirt surface.

Federal-Mogul Powertrains says that its latest EcoTough coatings for gasoline and diesel engines take this a step further, reducing skirt wear in a gasoline engine by up to 40 percent compared to today’s market standard.

The diesel variant of the coating, called EcoTough-D is a polymer-based coating reinforced with short carbon fibers with embedded graphite as the solid lubricant, developed for both aluminum and steel diesel pistons and can be used in both passenger vehicles and heavy commercial vehicles.

It reduces piston friction by as much as 35 percent compared to conventional coatings and improves wear resistance by up to 30 percent.

Federal-Mogul expects both coatings to be on the market in 2017.
