How to Distinguish Between the Brake and Accelerator?

[McRuby]

The brake and accelerator can be distinguished as follows: 1. The accelerator pedal is located on the far right of the car's foot pedals, while the brake pedal is to the left of the accelerator pedal. 2. In the case of a manual transmission car, there is also a clutch pedal, which is positioned on the far left, with the brake pedal situated between the clutch pedal and the accelerator pedal. Below is an extension of knowledge about car pedals: 1. The accelerator and brake pedals are commonly used for driving. The accelerator pedal does not directly control the fuel injection volume. 2. The accelerator pedal controls the throttle valve opening. When the accelerator pedal is pressed, the throttle valve opens wider, and the ECU detects an increase in air entering the engine, subsequently instructing the fuel injection system to inject more fuel. 3. Pressing the brake pedal activates the master cylinder, which uses brake fluid to push the brake calipers. The pistons in the calipers then press the brake pads against the brake discs, converting kinetic energy into heat energy, thereby slowing down the car.
