Cylinder
•Material: primary aluminium alloy with a high content of hardened and tempered silicon, cylinder liner with silicon carbide coating in a galvanic nickel die and crossed smoothing with two diamond passages with very limited tolerances.
•Machining: on machine tools with high precision numerical control.
•Cylinder-piston connection with an allowance of 0.05 mm.
•Recalculated and upgraded heat exchange surfaces.

Piston
•Ultra compact with 3 rings.
•Material: special aluminium alloy with high silicon content, low thermal expansion and a tin facing on the sliding surfaces.
•Machining on machine tools with numerical control.
•Lightened and reinforced.
•Upgraded heat exchange surfaces.

Piston rings
•Compression - special rings with high sliding ease and very high mechanical resistance, in chromium-plated S10 spheroidal cast-iron.
•1st scraper - ring in chromium-plated S10 spheroidal cast iron.
•2nd three - piece scraper ring made of chromium-plated steel alloy.
