Malossi Intake Manifold D 19.5x24x31 tilted 15° center distance 46 for PHBG carburetors

The Malossi intake manifold Ø 19.5x24x31 inclined 15° with a center distance of 46 for PHBG carburetors is an essential component for optimizing engine performance. This intake manifold serves as an access corridor for the air-fuel mixture into the engine through the reed valve.

The overall engine efficiency 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 loss. It is important to avoid sudden increases in section and sharp edges along the mixture's path.

Furthermore, 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 offer maximum performance within a specific range of engine speeds (tuned manifold). Additionally, it also supports the carburetor and dampens vibrations transmitted from the crankcase to the carburetor, preventing fuel and air emulsion in the carburetor float bowl.

Malossi, with its decades of experience in engine fuel systems, has developed a new line of rubber and aluminum alloy manifolds for the next generation of scooters. These manifolds have been tested and developed by Malossi's 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 fuels. This construction ensures significant rigidity in the mounting base to the crankcase and good elasticity of the manifold body.
