China OEM Engine Starter Motor Products - over running alternator pulley F-228824 – RNA

What are the benefits of installing a one-way pulley? 1. The performance improvement of front-end accessory belt drive system is to reduce belt vibration

Reduce belt tension

Reduce the tensioning stroke of the belt tensioner

Improve belt life

Reduce belt drive noise

Increase the speed of the alternator at engine idle

Improve the belt drive noise and slip of the generator when the car is shifting gears. When the gearbox is shifting up and down, it doesn’t have the strong stumbling and impact. The response to shifting up and down should be a little faster. The idling jitter and sound should be light, which can improve the driving feeling. 2. When the engine speed is less than 2000 rpm, The alternator one-way pulley can decouple the moment of inertia of the generator from the accessory belt system at the front of the engine. Whether the decoupling function of the one-way pulley works depends on the load of the engine (amplitude of torsional vibration), the moment of inertia and load of the generator. In addition, the unidirectional pulley decouples the moment of inertia of the generator when the engine speed drops sharply due to vehicle shifting.
