|Steel pistons reduce weight, friction
What: Monotherm steel pistons for passenger car diesel engines
Innovation: Aluminum pistons are the standard for diesel engines. Mahle's forged steel piston and accompanying pin assembly are lighter than an aluminum assembly. And the steel piston operates with 5 percent less friction than aluminum, helping automakers to meet goals for carbon dioxide reduction.
