How Do Carburetors Work?

carburetorA vehicle’s carburetor fulfills three major purposes. To begin, it mixes gas and air to make a combination that is highly combustible. It also regulates the ratio of fuel and air. Finally, it controls an engine’s speed. Understanding how a carburetor works will help a person gain better control of the vehicle and make the most with the gasoline that is used.


The Purpose Of A Carburetor


The major goal of a carburetor is to combine the perfect amount of gas and air, so the engine runs as smoothly as possible. Without enough fuel, the engine will run lean and lead to damage. With too much fuel, the engine will run rich, and fuel will be wasted. Older vehicles all have carburetors because they are inexpensive and simple. Newer vehicles commonly come with fuel injection in place of a carburetor in order to assure low emissions and better efficiency.


What Makes A Carburetor Work?


A carburetor works according to the Bernoulli’s principle, which states that the faster air moves, the lower static pressure becomes, and the higher dynamic pressure rises. Basically, a carburetor is a tube. There is an adjustable feature called a throttle plate, which controls the amount of air that can get through the tube. Part of this tube contains a venture, or narrowing. This narrowing part creates a vacuum. In this narrowing, there is also a jet that allows fuel to be drawn. This is all a simple concept that lends better control.


The entire principle behind an older engine rests on a carburetor. It only takes a small amount of gas for combustion to take place, but it is essential to have the correct mixture of air with gas. In the end, this proper combination will assure the highest level of fuel efficiency and will also keep the engine running smoothly.
