MORE INFORMATION

INTAKE MANIFOLDS
The intake manifold is the access corridor for the air-petrol mixture into the engine through the port formed by the reed valve.

The total efficiency of an engine is calculated as the product of various partial efficiencies which are:
- volumetric efficiency
- thermodynamic efficiency
- mechanical performance
The volumetric efficiency indicates the ratio between the quantity in volume of mixture that can be introduced into the combustion chamber and the engine displacement.

ATTENTION: in order to mount the mhr manifolds it is necessary to perform some small modifications to the surrounding plastic.

INTAKE MANIFOLDS

The intake manifold is the access corridor for the air-petrol mixture into the engine through the port formed by the reed valve.

The total efficiency of an engine is calculated as the product of various partial efficiencies which are:
-  volumetric efficiency
- thermodynamic efficiency
- mechanical performance

The volumetric efficiency indicates the ratio between the quantity in volume of mixture that can be introduced into the combustion chamber and the engine displacement.

One of the main factors that influences the volumetric efficiency is the friction loss that meets the inlet fluid (air-petrol mixture) from the air filter up to the combustion chamber, therefore one of the components that significantly influences this loss is the manifold. aspiration, as all the incoming mixture must pass through it with the minimum possible loss  , for this reason it is absolutely necessary to avoid sudden increases in section and sharp edges along the path of the mixture.
Another function of the intake manifold is to act as a storage tank for the fresh charge  , since the column of mixture, traveling at a certain speed, takes a certain time to stop when the reed valve closes and therefore the mixture accumulates in the manifold, compressing itself against the reeds. For this reason, each collector has its own well-defined range of revolutions within which it expresses the maximum efficiency (tuned collector).
Furthermore, the manifold performs the task of supporting the carburettor by connecting it to the crankcase or to the cylinder  therefore it also has, if required, the task of damping the vibrations transmitted from the crankcase to the carburettor, avoiding the phenomenon of petrol and air emulsion in the carburettor bowl.
Therefore, this apparently simple component requires considerable study, in order to fully exploit all its qualities, a result that Malossi technicians have perfectly achieved.
Thanks to its decades of experience in fuel systems for engines, Malossi has created a new line of rubber and aluminum alloy manifolds for the new generation of scooters, tested and developed by the Malossi experience department, both on the road and on the circuits. of race.
In particular, the Malossi rubber manifolds have a composite structure as they are built starting from an aluminum insert that is incorporated in a particular plastic material that cannot be attacked by oils and gasolines, thus guaranteeing considerable rigidity of the fixing base to the crankcase and a good elasticity of the collector body.
