• Specifiion

• Functions

1. Power Distribution: Transmits crankshaft power to auxiliary components, enabling functions like coolant circulation (water pump), electrical power generation (alternator), and compressed air production (air compressor).

2.Speed Regulation: Its diameter is calibrated to control the speed of driven components, ensuring they operate within their optimal range (e.g., an alternator must spin fast enough to generate sufficient electricity at idle).

3.Vibration Reduction: Balanced design minimizes rotational vibration, reducing noise and extending the life of belts, bearings, and other drive system components.

4.System Synchronization: Ensures auxiliary components work in harmony with engine speed, preventing mismatched operation (e.g., a water pump that is too slow could cause engine overheating).
