Structure and editing
The cylinder is made of a primary aluminum alloy with a high proportion of hardened and tempered silicon. The cylinder liner has a silicon carbide coating in an electroplated nickel die. Cross-smoothing with two diamond passages and very tight tolerances supports the precise cylinder-piston connection with a tolerance of 0.05 mm. Machining is carried out on machine tools with high-precision numerical control.
The ultra-compact piston made of a special aluminum alloy with a high silicon content is light and reinforced. Its sliding surfaces have a tin layer. Improved heat exchange surfaces can be found on the cylinder and piston. The piston works with three rings: a nitrided and chrome-plated steel ring, a special ring made of cast iron and a three-part wiper ring made of special chrome-plated steel alloy.
