Malossi Manifold D 34x45 Rear Inclined

The Malossi Ø 34x45 rear inclined intake manifold is an essential component for the proper functioning of the engine. It is the 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, thermodynamic, and mechanical efficiency.

Volumetric efficiency represents the ratio between the amount of mixture entering the combustion chamber and the engine displacement. To achieve high volumetric efficiency, it is crucial to minimize losses due to friction along the mixture path. The intake manifold plays a crucial role in this process as it must allow the passage of the mixture with minimal loss. It is important to avoid abrupt section increases and sharp edges along the path.

In addition, the intake manifold 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 specific range of engine speeds in which it expresses maximum efficiency.

The manifold also serves the purpose of connecting the carburetor to the engine crankcase or cylinder and dampening vibrations. This prevents the emulsion of fuel and air in the carburetor float bowl. 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 R&D 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 ensures a rigid attachment base to the crankcase and good elasticity of the manifold body. Thanks to careful study and the expertise of Malossi technicians, these manifolds offer optimal and long-lasting performance.
