Malossi Manifold D 15x19 inclined

The Malossi Ø 15x19 inclined intake manifold is an essential component for the intake of the air-fuel mixture into the engine. Its design has been studied to ensure maximum volumetric efficiency, which represents the ratio between the amount of mixture introduced into the combustion chamber and the engine displacement.

One of the factors that affects volumetric efficiency is the friction encountered by the mixture along the path, from the air filter to the combustion chamber. The intake manifold is designed to minimize these losses, avoiding abrupt changes in section and sharp edges along the path.

In addition, the manifold also serves the function of accumulating fresh charge, allowing the mixture to compress against the reeds when the reed valve closes. Each manifold has a range of engine speeds in which it expresses maximum performance, and is therefore tuned to optimize performance.

The intake manifold also connects the carburetor to the engine crankcase or cylinder and serves the task of dampening vibrations, preventing the emulsion of fuel and air in the carburetor float bowl.

Thanks to its experience in the field of engine fuel systems, Malossi has developed a new line of rubber and aluminum alloy manifolds for the latest generation scooters. These manifolds have been tested and developed by the Malossi experience 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 a rigid attachment base to the crankcase and good elasticity of the manifold body.
