MALOSSI 3117163 MHR Processing Ø63 Aluminum CVF2 Sp. Ø 15 Vespa Cosa 125 2T

Description: DESCRIPTIONTHERMAL GROUP Ø 63 IN ALUMINUM The completely new thermal group was born, designed in every part to obtain the maximum result in terms of performance and duration. Every aspect of the system has been studied to maximize mechanical resistance, fluid dynamics and improve combustion: the result is a top-of-the-range kit in terms of construction quality and technological advancement. TECHNICAL FEATURESCylinderMade completely from scratch, in high-strength aluminum alloy and barrel with nickel-chromium coating. Composed of a central core with constant thickness around the barrel and the transfers, it guarantees a constant heat exchange, therefore a controlled gas injection temperature in the chamber and an optimal heat exchange at the exhaust, it has aerodynamically profiled cooling fins around the core designed to be penetrated with the best possible efficiency by the cooling air. The major innovation is represented by the completely revised and updated transfer system, introducing the CVF according to the latest updates obtained thanks to the experience gained from competitions. The transfer ports have now been raised to 7, a distinctive feature of the Malossi kits, thanks to which it has been possible to obtain the best fluid dynamic performance.The connection to the muffler is made possible by a flange-fitting assembly fixed to the cylinder by means of 4 cylindrical head screws and a sealing Oring to the exhaust pipe inserted to avoid any leakage from the thermal unit. With this extremely simple assembly system, it is possible to house all types of mufflers on the market with a Ø 37 inlet with maximum resistance, avoiding any unscrewing or rotation problems due to vehicle vibrations.The connection with the head is instead now achieved by means of a high precision centering on the support surfaces obtained with numerical control machines. A set of multi-thickness base gaskets is supplied to allow the user to adjust the compression adapting it to the most varied uses. PistonCast with an innovative material, consisting of a steel core coated with an aluminum and silicon alloy, which gives extreme lightness as well as excellent resistance to corrosion, even at high temperatures and a reflection of the heat derived from combustion, the heat flow is therefore directed towards the dissipation surfaces, favoring the cooling of the combustion chamber and its maintenance within the optimal temperature range. In the inner part of the shell it has ribs immersed in the fusion with which the right strengthening in the most mechanically stressed areas was obtained, while allowing maximum lightening of the piston. The windows at the rear and the diametrical grooves, on the other hand, guarantee the maximum possible flow of fresh charge towards the cylinder ports. HeadAnother revolution in the construction philosophy of 2-stroke engines: the cooling fins have been sized to optimize the heat flow from the chamber to the outside but are now also profiled according to modern simulations to allow the maximum possible penetration of the air coming from the system cooling system, which now touches the head with an increase in efficiency of over 10% compared to a traditional system with straight fins.The characteristic hemispherical profile combustion chamber is machined with tolerances to the tenth of a millimeter and develops a high turbulence combustion, with pressure peaks calculated at the most suitable regimes to obtain the maximum performance in terms of torque and power, the very high temperatures that occur they reach in this particular border area between head and cylinder which are often the origin of hot spots and detonations are regulated thanks to an aerospace mold solution: a depression chamber duct made with two bulkheads and a series of inlet and outlet deflectors . Which convey, thanks also to a precise surface profile, a part of the cooling air forcing it not only to touch the surfaces but also to expand by decreasing, thanks to a precise physical principle, the pressure and therefore the temperature of the walls bordering the chamber of burst.
