Which car part regulates the engine’s air intake to control the engine's speed?
Correct Incorrect The throttle body is a key component in the air intake system, regulating the amount of air entering the engine, which directly affects the engine's power and efficiency. When the accelerator pedal is pressed, the throttle body opens to allow more air into the engine, increasing speed and power. Modern vehicles often use electronic throttle control, replacing the traditional cable system with electronic sensors for improved precision and fuel efficiency.
