Malossi Manifold D 20.8x24 tilted for crankcase 57 5208 - 57 6548

The Malossi Ø 20.8x24 inclined intake manifold is a fundamental component for the engine's fuel system. This intake manifold allows the entry of the air-fuel mixture into the combustion chamber through the reed valve. Its design has been studied to maximize the engine's efficiency, considering various factors such as volumetric, thermodynamic, and mechanical performance.

The volumetric performance represents the ratio between the amount of mixture entering the combustion chamber and the engine's displacement. To achieve optimal volumetric performance, it is essential to minimize losses due to friction along the mixture's path, from the air filter to the combustion chamber. The intake manifold plays a crucial role in this process, allowing the fluid to pass through it with minimal losses. Therefore, it is important to avoid sudden increases in section and sharp edges along the mixture's path.

In addition to improving volumetric performance, the intake manifold also functions as an accumulator for the fresh charge of the mixture. When the reed valve closes, the mixture accumulates in the manifold, compressing against the reeds. This allows for maximum performance within a specific engine speed range.

Furthermore, the intake manifold connects the carburetor to the engine crankcase or cylinder and also dampens vibrations transmitted from the crankcase to the carburetor. This prevents the phenomenon of fuel and air emulsion in the carburetor float bowl.

Malossi, with its extensive experience in the field of engine fuel systems, has developed a new line of rubber and aluminum alloy manifolds for the latest generation of scooters. These manifolds have been tested and developed by Malossi's experience department, both on the road and on race circuits. In particular, Malossi's rubber manifolds feature a composite structure, with an aluminum insert embedded in a plastic material resistant to oils and fuels. This ensures a rigid attachment base to the crankcase and good elasticity of the manifold body.

Therefore, the Malossi Ø 20.8x24 inclined intake manifold is a high-quality component designed to maximize engine performance and ensure optimal fuel system efficiency.
