Where is the throttle, what is its use and how to adjust it?

The throttle valve is located at the junction of the intake manifold and the air cleaner. Generally, there are few adjustments to cars now. Its function is basically equivalent to that of the previous carburetor. See Baidu Encyclopedia-Throttle for details.

Throttle: A controllable valve used to control air entering the engine. After entering the intake pipe, it is mixed with gasoline (different cars have different design mixing parts) to become combustible mixture, which participates in combustion and does work. Four-stroke gasoline engines are generally like this. Throttle is the most important component in today's EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the accelerator should be removed for cleaning is the focus of discussion among car owners.
