Compensation for belt length changes: The engine will follow the changes in the working conditions of the car such as acceleration, deceleration, idling, and sudden braking. The belt will also change accordingly. The belt tensioner idler kit can automatically compensate for the change in belt length. Through the tensioner adjustment device, the belt tension is adjusted in real time to ensure that the belt always maintains the appropriate tension to adapt to different working conditions
