Is the throttle and throttle of an engine the same concept?

This is not a concept. Simply put, the throttle controls the air volume and the throttle controls the oil volume.

Throttle is a controllable valve, which is used to control air to enter the engine. After entering the intake pipe, it is mixed with gasoline (different models of 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 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.

A device for controlling fuel supply on an internal combustion engine, in which a driver controls the throttle opening of the engine by controlling the amount of accelerator pedal pedaling, controls the intake air volume, and controls the fuel quantity through a computer, thereby controlling the engine speed.
