Structure of cylinder and piston

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 electroplated nickel form. A crossed smoothing with two diamond passes and very limited tolerances complements the processing on numerically controlled high-precision machines.

The ultra-compact piston has 3 rings, is made of a special aluminum alloy with a high silicon content and has low thermal expansion. The sliding surfaces have a tin coating. The piston is reduced in weight and reinforced; its heat exchange surfaces are improved. Special rings with high sliding properties and very high mechanical strength complement the piston design.
