We just learned about the Carburetor that helps bring the right mix of gas and air to the engine.
Another part of a car is a Fuel Injector.
A fuel injection does the same job as a carburetor, but it works a little differently.
The carburetor mixes up the gas and air and then sends the mixture over to the engine.
A fuel injection system instead sends the air and gas right into the engine, and it has something like a small computer that controls how much fuel and air goes in at just the right time and amount to make the engine work.
