Cut noise, friction and wear with EcoTough

Federal-Mogul Powertrain has introduced EcoTough-D, an innovative piston skirt coating. Based on previous EcoTough coatings, it reduces engine friction, wear and noise while dealing with the challenging loads and temperatures that exist in today’s smaller, turbocharged diesel engines.

The coating suits both aluminium and steel pistons, and sample pistons are completing validation programmes with vehicle manufacturers. EcoTough-D reduces piston friction by as much as 35% compared to conventional coatings, and wear resistance by up to 30%.

The piston pin and piston skirt account for around 17% of engine frictional losses.
