Article information
CYLINDER KIT MHR modular head
CYLINDER
- Material: special aluminum alloy with a high content of silicon and titanium, guaranteeing an exceptional tensile strength even at high temperatures.
- Heat treatment: special cooling and stabilizing treatment gives the material a high strength and toughness and to ensure that the size and mechanical specifications remain unchanged at temperatures up to 250 ° C.
- Chip-making process shall be carried out on NC machining with extremely limited tolerance size and shape (roundness, squareness).
- Inside surface layer: made by using silicon carbide in a nickel matrix with a heat treatment extreme hardness (about 600 HV0, 1 / 5) and excellent wear resistance.
- Internal machining of the cylinder: using special machines that a certain degree of finish of the cylinder wall roughness corresponds to the angles in the design (special grinding process using stone) as possible.
- Intake and exhaust diagrams: Developed and manufactured specifically for racing. The definition of the inlet and exhaust diagrams have a significant effort from our engineers, both on engine test stands and the track where the trophy is held.
PISTON
- Material: special aluminum alloy with a very high content of silicon and titanium, both excellent heat resistance and tensile strength to ensure variation in temperature.
- External coating: graphite coating that provides a low friction coefficient.
- Structure: reinforced to protect against the pressure of cylinder units for use in the top-level league, yet light enough inertial force to reduce
PISTON RING
Ring in highly ductile iron with ground, durable, hard chrome plated metal spray coating on the contact surface.
HEAD
The new modular Malossi head is designed to ensure that a remarkably high temperature engine developed a very high specific power for racing is abolished.
It consists of a cup of specially hardened and tempered aluminum alloy with a high silicon content that is directly attached to the cylinder. It enveloped the entire exterior of the coolant that ensures a very large heat exchange. In addition, detached from the walls inside the head free to the expansion of the cylinder to follow.
The combustion chamber is made entirely using numerical control machines to shape and size tolerances to ensure that tolerance within just one hundredth of a millimeter is.
The modular system is completed with a head cover on top of the cylinder, this ensures that the coolant is completely sealed.
The geometry and the diameter of the cylinder combustion chamber for this unit are designed for use in the Trophy and Scooter Scooter Speed Cross Trophy.
