Malossi Intake Manifold D 19 rigid MHR

The Malossi Ø 19 rigid MHR intake manifold is a fundamental component for optimizing engine performance. This intake manifold allows the passage of the air-fuel mixture into the engine through the reed valve.

The overall efficiency of the engine depends on various factors, including volumetric, thermodynamic, and mechanical efficiency. Volumetric efficiency represents the ratio between the amount of mixture introduced into the combustion chamber and the engine displacement.

The intake manifold plays a key role in volumetric efficiency, as it must allow the passage of the mixture with minimal loss. To avoid losses due to friction along the mixture path, it is essential to avoid sudden increases in section and sharp edges in the manifold.

In addition, the intake manifold also acts as a reservoir for the fresh charge, allowing the mixture to accumulate and compress against the reeds when the reed valve closes.

This manifold is designed to support the carburetor, connecting it to the engine crankcase or cylinder. Furthermore, it is able to dampen vibrations transmitted from the crankcase to the carburetor, preventing the emulsion of fuel and air in the carburetor float bowl.

Malossi technicians have dedicated considerable study to the design of this component in order to fully exploit all its qualities. Malossi, with its extensive experience in the field of engine fuel systems, has developed a new line of rubber and aluminum alloy manifolds for the new 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 considerable rigidity in the mounting base to the crankcase and good elasticity of the manifold body.
