Intake manifold from Reed Valve made of aluminium and rubber composite, flow-optimized for modern reed valve and carburettor tuning setups.

The intake manifold is the inlet channel for the air/fuel mixture through the reed valve into the Engine and has a decisive influence on volumetric performance. Flow losses between the Carburettor and combustion chamber should be kept as low as possible, which is why abrupt diameter changes and sharp angles in the Exhaust Manifold are avoided. At the same time, it serves as a storage chamber for the mixture flowing in and is tuned to a defined speed range. MALOSSI draws on many years of experience in the field of supply systems and has developed a new manifold line made of aluminum alloy and special Oil and petrol-resistant Rubber, which has been tested on the road and race track and combines flow, stability and durability.

• Flow-optimized intake duct for higher volumetric performance
• Multi-piece construction made of aluminum and elastic, fuel-resistant material
• Silencers vibrations and stabilizes mixture formation
• Exhaust Manifold tuned to defined speed ranges

The total output of an Engine is made up of various partial outputs, including the volumetric output. It describes the ratio between the amount of mixture in the combustion chamber expressed in volume and the actual displacement. The most important influencing factors include the frictional losses of the air-fuel mixture on its way from the Air Filter to the combustion chamber. The intake manifold plays a central role here: it must guide the mixture with the lowest possible losses, which is why large cross-sectional jumps and sharp deflections are avoided.

The Exhaust Manifold also acts as a storage chamber for the freshly aspirated mixture. As the mixture column moves at speed, it needs a certain amount of time to come to a standstill when the reed valve locks. The mixture accumulates in the Exhaust Manifold, presses against the vanes and thus contributes significantly to the tuned speed range in which the Engine develops its maximum power. At the same time, the Exhaust Manifold connects the Carburettor and Crankcase or Cylinder and serves as a Holder. An elastic design helps to keep vibrations away from the carburettor and prevents the emulsion of air and fuel in the carburettor tank.

MALOSSI combines a stable aluminum insert with a special plastic material that is resistant to Oil and petrol. The result is a component with high rigidity in the mounting area and the necessary elasticity in the Exhaust Manifold, which combines effort and know-how from theoretical design and practical testing in a seemingly simple but highly effective part.
