The Malossi intake manifold Ø 20x24 is specifically designed for PHBG 19.5 carburetors. This intake manifold acts as an access corridor for the air-fuel mixture into the engine through the reed valve. The overall performance of the engine depends on various factors, including volumetric efficiency, thermodynamic efficiency, and mechanical efficiency.
Volumetric efficiency represents the ratio of the amount of mixture entering the combustion chamber to the engine displacement. One of the main influences on volumetric efficiency is the friction that the fluid encounters during its path from the air filter to the combustion chamber. The intake manifold plays a fundamental role in minimizing this loss by avoiding abrupt changes in section and sharp edges along the mixture's path.
In addition, the intake manifold also acts as a reservoir for the fresh charge. When the reed valve closes, the mixture accumulates in the manifold, compressing against the reeds. Each manifold has a range of engine speeds in which it expresses maximum performance, so it is important to tune it correctly.
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 technicians have dedicated considerable study to this seemingly simple component to fully exploit all its qualities. Malossi, with its many years 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 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 construction ensures remarkable rigidity in the mounting base to the crankcase and good elasticity of the manifold body.
