The Core Role of Cable Branching Cables
2025-11-10
The distributor wire (also known as the ignition wire or high-voltage ignition wire) is a critical component of the traditional automotive ignition system. Its primary function is to precisely transmit the high voltage—typically reaching tens of thousands of volts—generated by the ignition coil directly to the spark plugs, igniting the air-fuel mixture inside the cylinders and thereby driving the engine's operation. The role of this component can be broken down as follows:
Voltage Conduction: Serving as the bridge between the ignition coil and the spark plug, it ensures lossless transmission of high voltage.
Ignition sequence distribution: In multi-cylinder engines, the spark plug wires are arranged in a specific order to deliver high-voltage electricity sequentially to each cylinder's spark plugs, ensuring coordinated engine operation.
Electromagnetic Shielding: Some split-cylinder wires feature a shielding design to minimize electromagnetic interference caused by high voltage, thereby reducing its impact on onboard electronic devices.
