Malossi Manifold D 19x24 center distance 42 mm for PHBG 19 carburetors

The Malossi intake manifold Ø 19x24 with a 42mm center distance for PHBG 19 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. Therefore, it is important to avoid abrupt increases in section and sharp edges along the mixture's path.

In addition, the intake manifold serves 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 by connecting it to the engine crankcase or cylinder. Furthermore, it is capable of dampening vibrations transmitted from the crankcase to the carburetor, preventing fuel and air emulsion in the carburetor float bowl.

Malossi technicians have dedicated considerable study to the design of this component in order to fully exploit all its qualities. With its many years of experience in the field of engine fuel systems, Malossi 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 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 significant rigidity in the mounting base to the crankcase and good elasticity of the manifold body.
