Pistons and piston rings

The compact, reinforced piston is made of a special aluminum alloy with a high silicon content, low thermal expansion and a tin layer on the sliding surfaces. Machining is carried out on numerically controlled machine tools. Improved heat exchange surfaces support the design of the piston.

The ring package includes a nitrided and chrome-plated steel ring as the first compression ring, a special cast iron ring as the second ring and a three-part wiper ring made of special chrome-plated steel alloy. The piston rings are designed for high sliding properties and high mechanical strength.
