The brake is called the brake pedal, what is the accelerator called?

Car accelerator pedal is also known as the throttle pedal. It is part of the car's fuel supply system. By controlling the amount of pedal depression, it regulates the engine throttle opening, controls the intake air volume, and the computer adjusts the fuel quantity, thereby controlling the engine speed. The positions of the brake, clutch, and accelerator are as follows: 1. Manual transmission cars: There are three pedals, from left to right, they are the clutch pedal, brake pedal, and accelerator pedal. 2. Automatic transmission cars: There are only two pedals, from left to right, they are the brake pedal and accelerator pedal. Relevant information about the brake, clutch, and accelerator is as follows: 1. Brake: As the name suggests, it is a mechanical braking device that can slow down the vehicle, also known as a decelerator. 2. Clutch: Located within the flywheel housing between the engine and the transmission, the clutch assembly is secured with screws to the rear plane of the flywheel. The output shaft of the clutch is the input shaft of the transmission. 3. Accelerator: Also known as the "throttle" or "gas pedal." It refers to the control device that manages the engine's power (thrust). In piston-type aircraft engines, the throttle controls the carburetor's throttle opening to adjust the cylinder's filling volume, thereby determining the engine's output power.
After driving for so many years, the accelerator is usually called the accelerator pedal, or more professionally, the throttle pedal. I use it dozens of times every day commuting to and from work. When driving slowly in the city, lightly pressing the accelerator to maintain a steady speed is crucial. In traffic jams, you have to control it carefully—just a bit more pressure and the car lurches forward. On the highway, the accelerator becomes the main tool for controlling speed. Many people don’t quite understand why it’s called the throttle pedal—simply put, it’s because it provides power to the engine, accelerating the vehicle. During routine maintenance, it’s important to check if the sensors on the accelerator pedal are clean, ensuring no dust buildup causes sticking, which could affect driving safety. Remember, the brake controls stopping, while the accelerator controls starting and speeding up—these two partners make driving smoother.
Back when I was learning to drive, the instructor repeatedly taught us to distinguish between the pedals. The throttle is the component responsible for accelerating, officially called the accelerator pedal or gas pedal. When I first got behind the wheel, I often confused it with the brake, almost making a fool of myself. The accelerator pedal is located on the right side of the driver's seat—stepping on it increases engine response and speeds up the car. Now, with more driving experience, I understand that the term "gas pedal" originates from its fuel regulation function. Early cars literally had a throttle valve, while modern vehicles achieve the same effect through electronic systems. During practice, beginners tend to press it too hard, so it's advisable to gently tap and slowly release to get used to the feel. By the way, avoid idling for too long when parked to save fuel, which is also better for the environment.
In mechanical terms, the accelerator is actually called the throttle pedal. I've disassembled several old car parts and found that it's connected to the throttle valve, controlling the air-fuel mixture entering the engine. When the pedal is pressed, it sends a signal via cable or electronic means to the ECU to adjust power output, making the car accelerate. Different car models have varying response speeds - some sports cars have highly sensitive throttle tuning where a slight tap causes rapid speed increase. During highway driving or overtaking, it's crucial for smooth speed buildup. During vehicle inspections, ensure the throttle operates smoothly without looseness or resistance, as this affects control precision. Simple maintenance can preserve optimal performance.
