Due to the lift motion of the piston and piston rings, their partner—the cylinder surface—is also subject to high mechanical loads and must withstand increased ignition pressures and speeds. In order to reduce wear, the running surface should be smooth and the lubrication between the sliding partners must be ensured. The type and quality of the running surface effects oil consumption as well as the wear of the two components. MAHLE offers a product range that is based on state-of-the-art technology. The development competence for individual solutions has grown over the years.
