Where is the car throttle controlled?

The car throttle controls the throttle valve. In carburetor vehicles, the throttle cable controls the opening of the throttle valve. Pressing the accelerator increases the throttle valve opening, allowing more air to flow into the cylinders. The carburetor injects fuel driven by the airflow, and as the throttle valve opening increases, the fuel supply also increases, raising the engine speed. Conversely, reducing the throttle decreases the engine speed. Below is additional information: Cable throttle: Whether it's a gasoline or diesel vehicle, there are still many vehicles with cable throttles on the market. The accelerator pedal directly controls the throttle valve opening via a cable, thereby regulating the intake air volume of the gasoline engine and adjusting the engine's power output. Electronic throttle: Electronic throttles no longer use mechanical connections. Instead, they use electrical signals to reflect the driver's intentions. The control system collects this pedal signal as one parameter to adjust the engine's power output, combining it with other parameters to determine the engine's output power.
As a driver who spends most of my time on the road, I believe the throttle controls the engine's air intake. When the accelerator pedal is pressed, the throttle valve opens accordingly, allowing more air to enter the combustion chamber. Then, the engine control unit increases the fuel injection based on the air volume, thereby raising the RPM and output power, enabling the car to accelerate. When cruising on the highway, gently adjusting the throttle helps maintain a steady speed, which greatly aids my long-distance driving safety. Once during a rainy night drive, I quickly released the throttle to slow down and avoid a collision, proving the importance of responsive control. In daily use, I always check if the throttle system is stuck, as blockages can cause power delays or increased fuel consumption. Remember not to press too hard—this not only saves fuel but also extends the engine's lifespan. After years of driving, I've developed the habit of regularly maintaining the throttle to ensure it operates smoothly without obstruction.
As a mechanical enthusiast who enjoys tinkering with cars, I've discovered that the throttle actually controls the opening and closing angle of the engine's throttle valve. When the pedal is pressed, the throttle valve opens wider, thereby increasing the airflow entering the cylinders. Subsequently, the engine control unit detects the change in airflow and commands the fuel injectors to spray more fuel, generating combustion power to propel the vehicle forward. This entire process regulates the engine's speed and torque, ultimately determining the vehicle's acceleration capability. In my view, understanding this principle can aid in diagnosing faults: for instance, a stuck throttle can cause abnormal air intake, leading to acceleration issues or a spike in fuel consumption. Keeping the throttle clean and lubricated is crucial, especially in high-temperature environments. I've found that cleaning the throttle valve every time I wash my car can prevent many minor issues.
As a novice just learning to drive, throttle control feels quite magical to me. It's used to adjust the vehicle speed: lightly pressing the pedal allows more air into the engine; pressing harder makes the car accelerate. Essentially, it controls a small valve in the intake system - when opened, more air flows in, making the engine work faster. Driving in the city, I've learned to apply gentle pressure so the car won't jerk forward, which saves fuel and ensures safety. After each practice session, I briefly check if the throttle moves smoothly to prevent sticking. Remember not to stomp on it too eagerly - gradual control works best.
