Given that the engine pace variations, the pulleys modify their width to keep up a relentless ratio among the engine as well as wheels. Because of this the motor can operate at its most effective stage, whatever the pace in the car.
So suppliers sidestep the challenge by artificially generating “gears” in their CVTs. Simply just, these are generally pre-established factors in which the designers determine which the two pulleys will be of specified relative sizes, just like ordinary gears.
