Difference between traditional ignition and electronically controlled ignition

Traditional ignition timing is controlled by mechanical control and vacuum control of ignition advance angle; Some ignition signals are triggered by platinum contacts, while others are controlled by Hall sensors or magnetoelectric sensors.

Because this ignition system has inaccurate ignition time, many faults and high maintenance rate, it can not meet the requirements of modern cars. Instead, it is an electronic ignition system, and the electronic ignition timing is controlled by a computer. After the computer receives the engine speed, load and other signals, the ignition unit controls the ignition time, while the ignition head in the distributor is only used for ignition, or the distributor is not used at all, and an independent high-voltage coil is used for direct ignition.

This ignition method not only cancels the distributor, but also cancels the high-voltage line connecting the spark plug. The ignition coil is directly connected with the spark plug, which makes the spark stronger.

Compared with traditional ignition, electronic ignition has the advantages of large ignition energy, accurate ignition time control, higher reliability and stronger durability. Under any engine working condition, the electronic ignition system can ensure the best ignition advance angle, so that the mixture entering the cylinder can be fully burned, which not only saves fuel, but also increases power and reduces exhaust pollution.
