Machining is carried out on numerically controlled machine tools. Revised heat exchange surfaces support the structural design of the cylinder. The ultra-compact piston has three rings, is made of a special aluminum alloy with a high silicon content and has low thermal expansion. The sliding surfaces are coated with tin; the piston is weight-reduced and reinforced.

Piston rings

The piston set includes special rings with high sliding properties and high mechanical strength: an I-compression ring made of nitrided and chrome-plated steel, a special cast ring and a three-part wiper ring made of special chrome-plated steel alloy. The piston compression is designed as racing.
