SINOCMP Product Specification Part Number: 5318120 C5318120 Part Name: Alternator Generator Model Applicated: for Cummins C5318120 ISF3.8 Engine An alternator is a mechanical device that converts other forms of energy into electrical energy. It reduces friction, vibration and noise. Ensure your equipment lasts long and runs quietly. An alternator recharges the battery while the car is driving, keeping the car fully operational throughout the trip. It provides a consistent and stable output voltage, preventing fluctuations that could damage sensitive electronic components. This ensures the proper functioning of essential systems such as ignition, lighting and entertainment systems. Each generator undergoes pressure/flow/high and low temperature fatigue/oscillation machine testing before leaving the factory, with over 10,000 hours or 100,000 miles of trouble-free operation experience.
