Carbureted vs Fuel Injected. In carbureted engines, the fuel/air mixture meets in the carburetor. The mixture then goes to each cylinder through the air intakes. In the fuel injected engine, the fuel and air do not mix until they reach the cylinder.
So, do any cars still use carburetors?
Carburetors on cars operated the same way. To start the car, you had to pull out the choke and let the engine warm up. Modern fuel injection systems don't require this warm-up period. There are some very obscure auto makers, primarily in Africa and Russia, who still build cars with carburetors.
What is the difference between a carburetor and throttle body?
A TBI system is similar to a carburetor in that one or two injectors are located in a central throttle body that supplies fuel to the engine through the intake manifold. Instead of using engine vacuum to siphon fuel through metering circuits as a carburetor does, fuel is sprayed into the manifold through the injectors.
What was used before fuel injection?
Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke. On petrol engines, fuel injection replaced carburetors from the 1980s onward.
