Carburetors were once the go-to technology for mixing fuel and air in a car’s engine. They worked by using a venturi to create a vacuum that drew air into the carburetor. The carburetor then added fuel in the right proportion, creating a mixture that was sent to the engine’s cylinders. This process made cars run smoothly and efficiently (via Car & Driver).
However, as technology evolved, fuel injection systems became the preferred choice for car manufacturers. Fuel injection systems are more precise and efficient, and they don’t require as much maintenance as carburetors. They work by using sensors to determine the right amount of fuel to add to the air, creating an optimal mixture for the engine. This has led to a decline in the use of carburetors in newer cars, but some car enthusiasts still prefer the simplicity of carburetors and enjoy working on older cars that use them.
