A vehicle with a carburetor has a venturi.
A carburetor mixes air and fuel in appropriate proportions. Air and Liquid fuel are the inputs to the carburetor at different points of the carburetor. Due to suction created by the working engine , atmosperic Air is accelerated through the venturi in the carburetor. Accelerating Air sucks Fuel into the venturi at its center from a level regulated liquid fuel pot in the carburetor,due to the venturi action. (Bernoulli's Principle) During the process of sucking the fuel is atomised /becomes a mist , as it enters the venturi. The atomised fuel then evaporates and mixes with the air uniformly. This uniform gaseous mixture of fuel and air is the out put of the carburetor. This gaseous mixture then enters into engine cylinders for combustion.
The flow of air in the carburetor venturi is restricted.

The 302 ( 5.0 L is fuel injected ) The 351 ( 5.8 L has a variable venturi carburetor )
this is the same in an older car. fuel is injected into the venturi, mixed with air, sent to the pistons, and- you are no longer working with carburetors. it is best if you research a car's carburetor.

Functionally, a carburetor adds air to fuel in order for it to explode. A straight fuel would not effectively burn in the cylinder without air being added. The classic carburetor works because of a mechanism known as the Venturi Effect. When the piston of the engine enters its "intake" cycle air is drawn in through the carburetor. This air passes through a small hole and over a jet. The air passes with enough velocity to create the Venturi Effect and, effectively, suck fuel from the jet. The "sprayed" fuel mixes with the air and is taken into the cylinder. See related links for a basic picture.
A venturi is also called a "jet pump", an "injector", or an "eductor". As a fluid velocity is increased, its pressure decreases. A venturi is sued to increase fluid velocity, to obtain the lower pressures necessary to draw in some other fluid. Commonly used to drain water beds using flow from a sink, to add chemicals to a water stream, and to add gasoline to an air stream (in older engines).
The venturi pool cleaner is more efficient in how it works. It pulls in as much water as the pump and doesn't increase energy costs. It works by pulling the water and debris through a filter like a normal system.
