The ignition system creates a spark discharge in each cylinder of the engine at a certain moment, which ignites the compressed fuel mixture. To create a spark in the ignition coil, the 12 V battery voltage is converted to a high ignition voltage of 30,000 V.
There is no ignition system on a diesel engine, since when air is compressed in the engine cylinders, the air heats up so much that after fuel injection, it spontaneously ignites.
The ignition system is an integral part of the engine management system. To determine the ignition timing, the control unit uses information stored in memory and information from sensors installed on the engine. The ignition system receives control signals from a Hall sensor or an impulse sensor. Additionally, the ignition timing is also corrected by the knock sensor signal, which is sensitive to pre-ignition and, accordingly, reduces the ignition timing.
The distribution of high voltage to the spark plugs of individual cylinders is carried out by means of electronically controlled elements that replace the traditional mechanical distributor with a distributor rotor. The ignition device has a separate ignition coil for each spark plug, which is mounted on the cylinder head.
The ignition system does not require maintenance during operation, except for the replacement of candles as part of maintenance.
When refueling a car with alternative fuel, engine power is reduced and fuel consumption increases.
Octane number (ROZ) fuel determines the anti-knock properties of the fuel.
When working on the electronic ignition device, precautions must be taken to avoid personal injury or damage to the ignition device.
