Pipe of admission MALOSSI MHR Ø22x28 rubber racing on minarelli horizontal (nitro, aerox, ovetto, neos ...)

Female rubber pipe, aluminum pedestal base embedded in a rubber. For all your large configurations. You can ask a carburetor 21 to 25mm at best, advised by MHR Malossi carburettor:

DELLORTO

-PHBG 15 to 21mm

-PHBG Racing 19 and 21mm

-PHVB 22mm

-PHBL 22 to 25mm

The outer diameter of fixing carburettor for male is 28 to 30mm, the pipe then passes to finish 25mm 28mm therefore has a perfect venturisation. Its soft material provides total vibration absorption, the total size of 29mm short approach maximum engine carburetor and still offers a performance boost as well as the respondent. It has no outlet to depression or separate lubrication. This is the pipe used for the cup Malossi MHR. Delivered with carburetor clamp, pipe gasket / valve is integrated in the pipe.

Carburetor mounting diameter (for male carburetor) d.28 with 30mm

Inner diameter after mounting: d.22mm

Outlet diameter valves against venturisation: d.25mm

malossi description for MHR:

The intake pipe is the access of the air fuel mixture led into the engine through the door represented by the valve.

The total efficiency of an engine is the result of several partial returns, namely:
- Volumetric efficiency
- The thermodynamic efficiency
- The mechanical efficiency

The volumetric efficiency is the ratio of the amount, ie d. mixing volume that we manage to introduce into the combustion chamber, and the engine displacement.

One of the main factors affecting volumetric efficiency is loss due to fluid friction (air fuel mixture) air filter up into the combustion chamber; it follows that a party who weighs considerably on this loss is the intake pipe. Given that all the intake mixture must pass through this component and this, minimizing the loss, it is imperative to avoid abrupt section increases and bends along the route of the mixture.
The intake pipe also serves as means of accumulation of unburned load. Indeed, since the mixing column going at a certain speed, it takes some time to stop when the valve is closed; it follows that a certain quantity of the mixture remains in the collector and is compressed against the slats. That's why every collector has a defined number of revolutions range within which it reaches its maximum efficiency (tuned pipe).
The pipe also serves to support the carburettor by connecting it to the crankcase or cylinder; when necessary, it must also absorb vibrations transmitted through the housing to the carburetor to prevent the phenomenon of gasoline and air emulsion in the carburetor bowl.
It is therefore understood that this component, apparently simple, demand a thorough review to make it possible to fully exploit all the qualities that Malossi engineers have completely succeeded.
Malossi, thanks to its long experience in power systems for motorcycles, achieved a new line of rubber and aluminum alloy pipes for the new generation of scooters, which have been tested and developed, both on road and on the race circuit by Malossi experience division.
The rubber pipes Malossi is particularly distinguished by their heterogeneous structure because they are made ​​from an aluminum part that is integrated into a special plastic unassailable by oils and gasoline, which provides outstanding stiffness the fixing base to the housing as well as good elasticity of the body of the pipe.
