What is the function of a distributor?

[Foster]

The function of an automotive distributor is to connect and disconnect the low-voltage current, and distribute the high voltage generated by the ignition coil to the spark plugs of each cylinder in the engine's firing order. In a battery ignition system, the distributor and the ignition device are usually mounted on the same shaft and driven by the camshaft. It also includes an ignition timing adjustment device and a capacitor, among other components. If damaged, precise ignition cannot be achieved, leading to reduced engine efficiency or failure to operate. Symptoms of a faulty distributor: If the automotive distributor is faulty, there will be no spark, and the engine will not operate properly or start. Common symptoms include difficulty starting, poor ignition, and high-voltage leakage. Additionally, the engine may exhibit knocking, shaking, poor acceleration, and abnormal exhaust smoke. How a distributor works: The distributor lug is connected to the camshaft. When the engine rotates, it drives the camshaft, which in turn drives the distributor. The opening and closing of the internal contacts within the distributor achieve the effect of cylinder-specific ignition.
