The cylinder liner has a crossed smoothing with two diamond passes and very limited tolerances. Machining is carried out on numerically controlled machine tools. Cylinder and piston are matched to each other with a tolerance of 0.05 mm. Revised heat exchange surfaces support the structural design of the cylinder.

Pistons and piston rings

The ultra-compact three-ring piston is made of a special aluminum alloy with a high silicon content and low thermal expansion. A tin coating on the sliding surfaces as well as the weight-reduced and reinforced design complement the design. The piston rings are designed for high sliding properties and very high mechanical strength. The ring set includes 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.
