Word forms: (regular plural) Venturis
( Automotive engineering : Vehicle components , Engine, transmission, and exhaust )
In a vehicle, a Venturi
is a nozzle
and lowers static
pressure in gases or vapors flowing through it.
Named after Italian physicist
If the Venturi is too large, the flow of air is slow and will not atomize sufficient fuel to make
a balanced mixture.
In the days before fuel-injection, the "Venturi" was a feature of carburetors. Without it fuel couldn’t be drawn from the tank to
mix with the flow of air.
The science teacher set up the convergent-divergent nozzle, with flexible pipes attached
to manometers, to demonstrate to his class the action of the Venturi.
