How is the throttle opening affected?

When we drive, the depth of stepping on the accelerator pedal is actually to control the accelerator opening. The deeper you step on the accelerator, the greater the throttle opening, the greater the intake of mixed gas and the higher the engine speed. Throttle opening is affected by hand intake. Specifically, the throttle opening refers to the opening of the engine throttle. The throttle valve of the automobile engine is operated by the driver with the accelerator pedal, which changes the air intake of the engine and thus controls the operation of the engine. Different throttle opening indicates different working states of the engine. Therefore, mastering the throttle control and adjusting the throttle opening are skills that we must pay attention to when driving.
