Relationship between throttle, throttle, engine speed, automobile torque and speed

Air flow meter and throttle control are only one aspect of speed. Vehicle speed is generally controlled by air intake system and ignition system. (Of course, we should also consider the resistance of the car body to air and the quality of vehicle parts, such as cylinder block, suspension and tires. ) that's basically it. The greater the torque, the better the speed and growth rate. As for the air flowmeter, as the name implies, it measures the intake air and is done by a computer. The fuel injection amount is controlled according to the fuel injection amount of the fuel injector. Most cars now have air flow meters, but they only measure data.
