Digital electronically controlled ignition system classification
The digital electronically controlled ignition system (ESA) is divided into two types, the distributor type and the distributorless type (DLI). The distributor type electronically controlled ignition system uses only one ignition coil to generate high voltage electricity, and then the distributors ignite the spark plugs of the battery cylinders in the order of ignition. Since the on-off operation of the primary coil of the ignition coil is carried out by the electronic ignition circuit, the distributor has eliminated the breaker device and only functions as a high-voltage power distribution.
