With the new INJECTION TECH range of products a new
chapter is written, an answer, the racing world was anticipating, to
satisfy the growing number of Malossi Trophy Races for 70cc scooters.
TECHNICAL FEATURES cylinder kits CAST IRON CYLINDER - Technology -
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 heat exchange surfaces. - Exhaust and transfer ports
designed and tested for maximum thermodynamic performance. - Shape and
surface texture dimensional checks. - Cylinder and piston selected for a
100% fit of 0.010-0.005 mm. - Checking of all the seals carried out.
ALUMINIUM CYLINDER - Technology - Cylinders obtained by gravity
die-casting in permanent steel moulds. - Material: hardened and tempered
high silicon content primary aluminium alloy. - Machining: on
numerically controlled high precision machine tools. - Cylinder liner
with silicon carbide metal-spray coating on a galvanic nickel matrix,
cross-honed with passes with diamonds for very tight tolerances. - Heat
exchange surfaces recalculated. - Exhaust and transfer ports designed
and tested for maximum thermodynamic performance. - Shape and surface
texture dimensional checks. - Cylinder and piston selected for a 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 - 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 (air-cooled models). -
Cooling circuit sections and paths recalculated and resized
(liquid-cooled models). - Machining: numerically controlled high
precision machines with diamond tools. - Surface rust prevention
treatment.
