Malossi Manifold D 15x19 for Malaguti RST 50cc

The Malossi intake manifold Ø 15x19 for Malaguti RST 50cc is an essential component for the proper functioning of the engine. This intake manifold allows the access of the air-fuel mixture into the engine through the reed valve.

The overall performance of the engine 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 abrupt changes in section and sharp edges along the path of the mixture.

In addition, the intake manifold acts as a reservoir for the fresh charge, allowing the mixture to compress against the reeds when the reed valve closes. This component has a specific range of RPM in which it expresses maximum efficiency.

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 manifolds are made with high-quality materials and have been tested and developed by the Malossi research department. The rubber manifolds feature a composite structure, with an aluminum insert embedded in a plastic material resistant to oils and fuels. This ensures a rigid mounting base and good elasticity of the manifold body.
