Malossi Manifold D 19x24 tilted interaxle 46/51 for SHBC 19 carburetors

The Malossi Ø 19x24 inclined intake manifold with a center distance of 46/51 for SHBC 19 carburetors is an essential component for optimizing the performance of Gilera 50cc motorcycles. This intake manifold serves as an access corridor for the air-fuel mixture into the engine through the reed valve.

The overall engine performance depends on various factors, including volumetric, thermodynamic, and mechanical efficiency. Volumetric efficiency represents the ratio between the amount of mixture entering 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 losses. Therefore, it is important to avoid sudden increases in section and sharp edges along the mixture's path.

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

The manifold also serves the purpose of connecting the carburetor to the engine crankcase or cylinder and can dampen vibrations transmitted from the crankcase to the carburetor, preventing fuel and air emulsion in the carburetor float bowl.

Malossi technicians have carefully studied this component to fully exploit all its qualities. With its years of experience in engine fuel systems, Malossi 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 feature a composite structure, with an aluminum insert embedded in a plastic material resistant to oils and gasoline. This ensures significant rigidity in the mounting base to the crankcase and good elasticity of the manifold body.
