Malossi Intake Manifold D 28x36 inclined for PHBH and VHST carburetors

The Malossi Ø 28x36 inclined intake manifold for PHBH and VHST carburetors is an essential component for the proper functioning of the engine. This intake manifold allows the passage of 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 indicates the amount of mixture that can enter the combustion chamber compared to the engine displacement. One of the main causes of volumetric efficiency loss is the friction encountered by the mixture along the path, 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 when the reed valve closes. Each manifold has a range of RPM in which it expresses maximum efficiency, so it is important that it is tuned to the engine.

The manifold also supports the carburetor, connecting it to the engine crankcase or cylinder. In this way, it prevents vibrations that could cause fuel and air emulsion in the carburetor float bowl.

Malossi manifolds have been developed and tested by the Malossi experience department, both on the road and on race circuits. They are made with a composite structure, combining an aluminum insert with a material resistant to oils and gasoline. This ensures a rigid attachment base to the crankcase and good elasticity of the manifold body.

The Malossi Ø 28x36 inclined intake manifold for PHBH and VHST carburetors is therefore a high-quality component, designed to maximize engine performance and ensure greater efficiency.
