Which part is actually controlled by stepping on the gas pedal?

It controls the throttle. \x0d\ The oil and gas vehicle controls the throttle opening through the throttle line. When the throttle opening increases, the air flow into the cylinder increases, and the air flow drives the carburetor to inject fuel. When the throttle opening increases, the fuel supply increases and the engine speed increases. Otherwise, the engine speed will be reduced. \x0d\ EFI vehicle is also a controllable throttle. Weigh the throttle body. There is a sensor next to the throttle, called the throttle position sensor. He can transmit the throttle opening signal to the driving computer in the form of voltage. According to this signal and other signals, the computer is driven to calculate the fuel injection quantity. Control the fuel injection quantity of the fuel injector. Like carburetor, the throttle opening is large and the fuel injection calculated by computer is also large. Engine speed will increase \x0d\ Do you understand?
