Malossi Manifold D 22/28 length 26 inclined Piaggio 50 2T

The Malossi Ø 22x28 inclined intake manifold is an essential component for Piaggio and Gilera 2-stroke 50cc 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 efficiency. The latter indicates 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.

In addition, the intake manifold also functions as a lung for storing fresh charge. When the reed valve closes, the mixture accumulates in the manifold, compressing against the reeds. This component is designed to ensure maximum performance within a specific range of RPM (tuned manifold).

In addition to these characteristics, the Malossi intake manifold also serves the purpose of connecting the carburetor to the engine crankcase or cylinder. In this way, it prevents vibrations that could cause fuel and air emulsion in the carburetor float bowl.

With its decades 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 Malossi's 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 gasoline. This ensures a rigid attachment base to the crankcase and good elasticity of the manifold body.
