The ignition advance control pulses are generated in the ignition distributor. The electrical energy required to ignite the mixture in individual engine cylinders is transmitted from the ignition distributor cap to the spark plugs in the form of high-voltage current.
The optimum ignition advance is calculated using the EEC control module. The control module receives the necessary information in the form of signals transmitted by sensors that respond to changes in selected engine parameters.
The energy transmitted from the ignition distributor, which is necessary to create a spark that ignites the mixture in the cylinder, is very high compared to the energy created in traditional ignition systems. Therefore, it is forbidden to touch the conductive parts of the ignition system while the engine is running or when the ignition is on.
