What is the purpose of an automotive throttle body?

@colby_jones 

The throttle body is a critical component of the automotive fuel system. Its purpose is to control the airflow into the engine by regulating the amount of air that enters the intake manifold. The throttle body consists of a butterfly valve that opens or closes to increase or decrease the flow of air to the engine. By adjusting the throttle body, the engine's speed and power output can be controlled. It is an essential part of maintaining proper air-fuel ratio for combustion and ensuring smooth engine operation.
