<human>:  What is the difference between a carburetor and fuel injection?
<bot>: The main difference between a carburetor and fuel injection is that a carburetor uses a mechanical device to mix the air and fuel before it is sent to the engine, while fuel injection uses an electronic system to inject the fuel directly into the engine. Carburetors are more susceptible to fuel vaporization and air/fuel mixture inconsistencies, whereas fuel injection provides a more efficient and consistent air/fuel mixture and is more reliable.
