Malossi Manifold D 26/30 length 31.5 inclined in NBR

The Malossi Ø 26x30 inclined intake manifold is an essential component for Piaggio and Gilera 50cc 2-stroke engines. This manifold serves as an access corridor for the air-fuel mixture into the engine through the reed valve.

The overall performance of an engine depends on various factors, including volumetric, thermodynamic, and mechanical efficiency. Volumetric efficiency indicates the ratio between the amount of mixture entering the combustion chamber and the engine displacement.

The intake manifold plays a crucial 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.

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 also serves the purpose of connecting the carburetor to the engine crankcase or cylinder, reducing vibrations and preventing fuel and air emulsion in the carburetor float bowl.

Malossi intake manifolds have been developed and tested by the Malossi research department, both on the road and on race circuits. The line of rubber and aluminum alloy manifolds offers a composite structure, with an aluminum insert embedded in a plastic material resistant to oils and fuels. This ensures a rigid attachment to the crankcase and good elasticity of the manifold body.

Thanks to their decades of experience in the field of engine fuel systems, Malossi has created high-quality intake manifolds that fully exploit all their qualities and improve engine performance.
