Beschreibung

Cylinder

• Material: special self-lubricating, wear-resistant, highly refined cast iron alloys, obtained by Shell Moulding gravity die-casting.
• Machining: on numerically controlled high precision machine tools.
• Recalculated and increased heat exchange surfaces.
• Exhaust and transfer ports designed and tuned for maximum thermodynamic performance.
• Dimensional and surface finish quality control performed according to Malossi's internal specifications.
• Cylinder and piston selected for a 100% fit of 0.010-0.005 mm.
• Checking of all the seals carried out.

Piston

• Material: special aluminium alloy with high silicon content and low thermal expansion.
• Machining: on numerically controlled machine tools.
• Lightened and strengthened.
• Heat exchange surfaces increased.

Piston rings

• Piston rings in very strong modular cast iron with ground, wear-resistant, hard chrome metal-spray coating on the contact surface.

Head

• Material: special die-cast aluminium alloy.
• Geometry of heat exchange surfaces recalculated and increased.
• Machining: numerically controlled high precision machines with diamond tools.
• Surface rust prevention treatment.
