5 Advantages of Electronic Ignition System

Electronic ignition system is one type of vehicle ignition system that is widely applied nowdays.

Why the electronic ignition become main option ?

Of course, electronic ignition systems have better performance in overall. It is very necessary in this time where energy-efficient cars are the new choices.

So what are the advantages of an electronic ignition system if it compared to breaker point ignition system?


At least we found 5 advantages of electronic ignition systems compared to conventional ignition systems.

1. Does not overload the engine combustion

The conventional ignition system uses a distributor device to drive the breaker point, and to distribute the secondary coil voltage to each spark plug. This distributor device is connected to the crankshaft engine, so it can be said that conventional ignition systems overload the engine's performance.

While the electronic ignition system does not overload the performance of the engine because it does not use mechanical devices, the electronic ignition system work electrically without power from crankshaft.

Breaker point, has been replaced using a transistor while the distributor is replaced with an ignition coil module. The device does not work mechanically but works electrically so that it does not overload the engine's performance.

This results in higher efficiency.

2. Bigger fire produced by the spark plug

Electronic ignition systems do not use distributors to distribute secondary voltage, but use a single coil where each coil will be connected directly to each spark plug.


It makes the connection shorter and no voltage is wasted as it is on the distributor, so the secondary voltage is used as a whole to ignite the spark plug. That makes the bigger fire on spark plug.

Then what is the effect if the fire on the spark plug is bigger?

Actually, larger fire is also not good for engine performance, but a clearer flame will certainly make combustion easier. In addition, no secondary voltage is wasted so that the input current on the coil can be reduced. So it saves more electricity.

3. No electrical energy is wasted

As I said above, the electronic ignition system is very effective and saves electricity because no voltage is wasted.

Wasted voltage can occur on improper plate connections. just like distributors, if we study about conventional ignition system we know that distributors work by rotating plates that have been exposed to secondary voltage, the plates will stick to each terminal in turn.

Of course there is the potential for wasted voltage if the connection plate with the terminal does not fit.

In addition, at the breaker point there is a spark. Sparks on the breaker point are absorbed by the capacitor, but from the capacitor the electric current that is absorbed is also directly neutralized to the ground so that there is wasted voltage.

By using electronic parts such as transistors, the above mechanism can be replaced with an electronic scheme without any loss-energy.

4. Suitable for high RPM

We know, the higher the engine RPM, the faster the sparking interval. The faster the sparking interval, the faster the induction interval on the coil.

Meanwhile, conventional ignition only has one ignition coil and one breaker point that will work at intervals according to the induction interval on the coil. So, when the RPM is high, the induction of the ignition coil is less than the maximum so that the fire produced is also relatively smaller.

But in electronic ignition, it has at least two ignition coil and has transistor according to the number of spark plugs. So that the induction interval for each ignition coil is not too fast even at high RPMs. it keeps the fire produced stable.

5. Zero maintenance

That means, the electronic ignition system does not require adjusment as in conventional ignition.

We know, conventional ignition systems use breaker points to trigger induction on the coil. In some time, the opening angle of the breaker point will shift because this is one of the moving parts and there is definitely a wear usage. So it needs an adjusment called dwell angle adjusment.

But in electronic ignition, it is not necessary. The reason, there is no moving part in electronic ignition. So it only relies on the quality of electronic component materials.

When one of the electronic components in the ignition is damaged, then repairs will be done. But as long as there is no damage, no treatment is needed.
