Best Answer

Electronic ignition typically doesn't use a rotating cam and ignition points. So there is less mechanical wear involved. The voltage produced at the spark plugs tends to be higher and a little "cleaner," electrically speaking. An ignition advance mechanism would not be heeded if the design of the ignition module or "computer" were sophisticated enough.

However, there is one major disadvantage. If there is an EMP (electromagnetic pulse) blast that takes out all sorts of electronic devices, such an ignition system would be destroyed. So after a major nuclear war, cars that use this likely won't run. However, if it has a standard points ignition, it can.

What is the primary advantage of the electronic ignition system over conventional ignition system is what?

The primary and basic advantage of electronic ignition system is that it reduces mechanical advantages and have more accuracy in delivering high voltage surges to the spark plug at higher RPM it has a fast switching device


What is the cause of on and off electricity in the distributor?

In a Pre-Electronic Ignition distributor, the "Points" are opened and closed by a rotating cam. This acts as a switch turning 12v on/off to the High Voltage Coil at the proper time. In an electronic ignition, a solid state circuit (transistors) performs the switching duty, replacing the Points/Cam as a timing circuit.
