1: Distribute high voltage electricity: Distribute the high voltage of the ignition coil to each spark plug in cylinder sequence to ensure accurate ignition timing.
2: Adjust ignition timing: By using centrifugal/vacuum devices, adjust the ignition timing according to the speed and load to optimize combustion.
3: Core components: including distributor head, distributor cover, and circuit breaker.
4: High voltage and wear-resistant: The distributor cover should be insulated to prevent leakage, and the distributor head contacts should be wear-resistant to avoid sparking.
5: Regular maintenance: clean contacts, check clearances, prevent carbon buildup/wear from causing poor ignition and affecting power.
