POLINI Carburettor CP ⌀ 21 Evolution

Ø 21 POLINI CP EVOLUTION CARBURETOR.
PURE ENERGY
The Ø 21 Polini CP Evolution Carburetor has been studied to exploit at the best the
racing engines and it achieves the best performance between 12.000 and 15.000 rpm.
The main feature is the working of the intake pipe made by the CNC machines that
exploits at the best the gases flow.
The manifold coupling is of Ø 28,5: this feature gives the possibility to fit a proper
manifold that better exploit the air brought by the new Ø 21 Polini CP Evolution
carburetor.
The carburetor is supplied with a flange to adapt the Polini Evolution filter with bigger
diameter too.
The inlet pipe is very short and it features an exclusive concentric design and a
geometry that optimize the air flows when the gases pass through.
The overflow of petrol in the atomizer has been studied to ensure correct flow
dynamic at every position of the throttle valve when opens.
The hole where the petrol enters and the larger needle allow the constant draft even
in the most extreme conditions.
The float level, completely made of plastic, and the needle seal are carefully controlled
in the production department to ensure the same standard of efficiency over time.
These features considerably simplify the setup of the carburetor.
Thanks to the extremely sophisticated calibration, the petrol-air flows, main and low
jets, have been designed to achieve the best performance with lower consumption.
The compact size of the new carburetor is the result of a careful and meticulous
management of the inner space and the maximum efficiency of all the components,
subjected to strict controls.
A prestigious project like this has required a deep synergy of competences in this
field. An extraordinary teamwork between the technical and the racing department to
reach the goal which is visible to everybody: a technologically advanced product and
of absolute reliability.
