Beschreibung

TECHNICAL SPECIFICATIONS

Cylinder

• Bore Ø 75.5 mm;
• Stroke 63 mm;
• Displacement 282;
• Compression ratio 12.5:1.
• 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

• Special rings with high sliding ease and very high mechanical resistance.
• I° ring compression in nitrided and chromium steel.
• II° special cast iron ring.
• Three - piece scraper ring made of chromiumplated special steel alloy.

Head

• Head made of gravity-fed cast aluminium alloy, tempered and sandblasted, machined within thousandth (mm) tolerances utilizing super precise work cells.
• Valve guides designed with new profile, made using a powdered metal sintering process (steel, phosphorous, carbon, copper and manganese).
• Valve seats made of cobalt-molybdenum steel alloy characterised by copper infiltration and a special heat/chemical treatment. Increased intake valve - ø 25 mm, made of a special steel alloy and a special heat/chemical treatment.
• Increased exhaust valve - ø 22.2 mm and made of Nimonich 80 material (Nickel, Chromium, Titanium, and Aluminium alloy).
• Exhaust and Intake valve springs made of Si-Cr oil-tempered and annealed steel, designed to operate optimally under increased loads due to increased engine power.
