Malossi Intake Manifold D 21x24 Inclined with Rigid Attachment

The Malossi Ø 21x24 inclined intake manifold with rigid attachment is a fundamental component for the correct functioning of the engine. This intake manifold allows the entry of the air-fuel mixture into the combustion chamber through the reed valve.

The total efficiency of the engine depends on various factors, including volumetric efficiency, thermodynamic efficiency, and mechanical efficiency. Volumetric efficiency represents the ratio between the amount of mixture introduced into the combustion chamber and 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. It is important to avoid sudden increases in section and sharp edges along the path of the mixture.

In addition, the intake manifold acts as an accumulation lung 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, and can also dampen vibrations transmitted from the crankcase to the carburetor, avoiding the emulsion of fuel and air in the carburetor float bowl.

Malossi technicians have carefully studied this component, fully exploiting 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 experience 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 guarantees considerable rigidity in the attachment base to the crankcase and good elasticity of the manifold body.
