Which Pedal is the Accelerator?

[KaydenLee]

Clutch pedal is on the far left, accelerator pedal is on the far right, and the brake pedal is in the middle. Here are the relevant details: 1. When the accelerator pedal is pressed, the throttle valve opening increases, allowing more air to enter the engine. At this point, the ECU commands the fuel injection system to inject more fuel, causing the engine speed to rise and the car to accelerate. Most modern vehicles use electronic throttle control, while older models used cable-operated throttle systems. 2. In electronic throttle systems, there is no physical connection between the accelerator pedal and the throttle valve. In contrast, cable-operated systems have a steel cable linking the two. Over time, carbon deposits can accumulate on the throttle valve, requiring periodic cleaning by car owners. 3. After cleaning the carbon deposits and reinstalling the throttle valve, it's necessary to perform an ECU reset. Otherwise, the engine may experience temporarily increased fuel consumption. The engine's ECU has strong adaptive learning capabilities - if carbon deposits are present, the ECU will adjust its control logic accordingly to manage the throttle valve with deposits.
