Malossi Manifold D 19x24 inclined for kit 20 6138

The Malossi Ø 19x24 inclined intake manifold is an essential component for the proper functioning of the engine. This intake manifold allows the air-fuel mixture to enter the combustion chamber through the reed valve. The overall performance of the engine depends on various factors, including volumetric, thermodynamic, and mechanical efficiency.

Volumetric efficiency represents the ratio between the amount of mixture introduced into the combustion chamber and the engine displacement. One of the main influences on this efficiency is the friction that the fluid encounters along the path, from the air filter to the combustion chamber. The intake manifold plays a fundamental role in this process, as it must allow the passage of the mixture with minimal loss. It is important to avoid abrupt changes in section and sharp edges along the mixture's path.

In addition, the intake manifold acts as a reservoir for the fresh charge. When the reed valve closes, the mixture accumulates in the manifold, compressing against the reeds. Each manifold has a range of engine speeds in which it expresses maximum efficiency, so it is important to tune it correctly.

The intake manifold also serves the purpose of connecting the carburetor to the engine crankcase or cylinder. Therefore, it must be able to dampen the vibrations transmitted from the crankcase to the carburetor, avoiding the emulsion of fuel and air in the carburetor float bowl.

With its many years of experience in engine fuel systems, Malossi has developed a new line of rubber and aluminum alloy manifolds for the scooters of the new generation. These manifolds have been tested and developed by the Malossi research department, both on the road and on race circuits. Malossi 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.
