How does the Fox throttle control the intake air flow?

Hello, throttle valves are generally divided into two categories! ! The first is the carburetor throttle, and the second is the resistance throttle! ! The principle is different! ! First: the throttle is used to adjust the engine speed. The bigger the throttle is, the lower the speed is! There is an air intake space next to it. When the throttle angle is large, the air pressure inside the engine is smaller than the air outside, and part of it goes in from the small space next to it to take away the corresponding gasoline! That is, the smaller the throttle, the more gasoline you take away! ! Second: resistance is a solar term, which is relatively simple! He's connected to the engine computer! He uses the voltage difference to adjust the speed of the starter! ! According to different companies, different styles of cars are different. There are generally two kinds! The voltage goes from high to low, and from low to high! !
