The Role of the Throttle Body in Engine Performance

A throttle body is a crucial part of an engine's air intake system, controlling the amount of air entering the combustion chamber. Positioned between the air filter and the intake manifold, it features a butterfly valve that opens and closes based on the accelerator pedal's position. This regulation of airflow is vital for maintaining the correct air-fuel mixture, ensuring efficient combustion, smooth engine performance, and optimal fuel efficiency. Without a properly functioning throttle body, an engine would struggle to run effectively, leading to poor performance and increased emissions.
