Malossi Manifold D 19x25 Inclined with Elastic Connection

The Malossi Ø 19x25 inclined intake manifold with elastic attachment is an essential component for the proper functioning of the engine. This intake manifold allows the entry of the air-fuel mixture into the engine through the reed valve.

The total efficiency of the engine depends on various factors, including volumetric efficiency, thermodynamic efficiency, and mechanical efficiency. Volumetric efficiency indicates the amount of mixture that can enter the combustion chamber compared to the engine displacement.

The intake manifold plays a fundamental role in volumetric efficiency, as it must allow the passage of the mixture with minimal loss. To avoid losses due to friction along the mixture path, it is important that the manifold does not have sudden increases in section or sharp edges.

In addition, the intake manifold acts as a reservoir for the fresh charge, allowing the mixture to accumulate and compress against the reeds when the reed valve closes.

This manifold is designed to support the carburetor, connecting it to the engine crankcase or cylinder. Furthermore, it is able to dampen the vibrations transmitted from the crankcase to the carburetor, preventing the emulsion of fuel and air in the carburetor float chamber.

Malossi technicians have dedicated considerable study to the development of this component in order to fully exploit all its qualities. Malossi, with its many years of experience in engine fuel systems, has developed a new line of rubber and aluminum alloy manifolds for the new generation of scooters. These manifolds have been tested and developed by the Malossi research department, both on the road and on race circuits.

Malossi rubber manifolds have a composite structure, with an aluminum insert embedded in a plastic material resistant to oils and fuels. This structure ensures considerable rigidity in the attachment base to the crankcase and good elasticity of the manifold body.
