Malossi Manifold D 20x24 for PHBG - SHB Carburetors

The Malossi intake manifold Ø 20x24 for PHBG - SHB carburetors is an essential component for the proper functioning of the engine. This intake manifold allows the entry of the air-fuel mixture into the combustion chamber through the reed valve.

The total efficiency of the engine depends on several factors, including volumetric efficiency, thermodynamic efficiency, and mechanical efficiency. Volumetric efficiency represents the ratio between the amount of mixture entering the combustion chamber and the engine displacement. One of the main factors that affects volumetric efficiency is friction loss that occurs along the path of the mixture, from the air filter to the combustion chamber. The intake manifold plays a fundamental role in this process, as it must allow the passage of the mixture with minimal loss.

In addition, the intake manifold acts as a reservoir for the fresh charge, allowing the mixture to accumulate and compress against the reeds when the reed valve closes. Each manifold has a specific range of engine speeds in which it offers maximum efficiency (tuned manifold).

In addition to these functions, the intake manifold connects the carburetor to the engine crankcase or cylinder and also dampens the vibrations transmitted from the crankcase to the carburetor, preventing the emulsion of fuel and air in the carburetor float bowl.

The Malossi intake manifold has been carefully designed by the company's experienced technicians, who have leveraged their decades of experience in the field of engine fuel systems. This new line of manifolds is made of rubber and aluminum alloy, materials that guarantee remarkable rigidity in the mounting base to the crankcase and good elasticity of the manifold body.

The Malossi manifolds have been tested and developed by the company's research department, both on the road and on race circuits, to ensure optimal performance and durability over time.
