Why is the area above the car accelerator pedal empty?

[KalebLee]

The reason why the area above the car accelerator pedal is empty is due to the installation of knee airbags and cost-saving measures. Below are relevant introductions about the car accelerator: Function of car accelerator: In gasoline engines, the accelerator does not control fuel injection volume, but rather regulates the throttle opening size. A smaller opening means less air-fuel mixture enters the cylinder, resulting in lower engine power output, and vice versa. Solution for heavy accelerator pedal: If the accelerator pedal feels heavy, you can perform a fuel system cleaning. Alternatively, try continuing to accelerate to see if the engine RPM increases but the speed doesn't. If this occurs, it might be due to a damaged sensor inside the transmission locking the overdrive gear.
