How many types of car accelerator pedals are there?

[StHaven]

There are two types of car accelerator pedals: suspended type and floor-mounted type. The floor-mounted pedal has its pivot at the bottom, allowing the entire foot to rest on it, which enhances control precision and reduces fatigue. The suspended accelerator pedal has its pivot at the top of the bracket, with a simpler lower structure, making the stepping action lighter. For gasoline vehicles, the accelerator pedal does not control fuel quantity but adjusts the engine's air intake by controlling the throttle valve opening, thereby regulating engine power output. For diesel vehicles, the accelerator pedal controls the fuel pump's fuel supply quantity.
