What is the function of electronic throttle mechanism? How does it work?

The function of electronic throttle mechanism is to realize the adjustment of engine air intake through electronic control. The working principle is to realize the accurate control of engine air intake through sensors, controllers, throttle drive devices and other components.

When the engine needs more air and fuel, the throttle will open to let air and fuel enter the engine; When the engine needs less air and fuel, the throttle will close, thus reducing the amount of air and fuel entering the engine.

The electronically controlled throttle mechanism can automatically adjust the size of the throttle according to the engine load detected by the sensor, so as to keep the engine in the best working condition.
