What are the different types of ignition systems?
Currently, there are four types of ignition systems used in most cars and trucks, by order of invention: conventional breaker-point (mechanical) ignitions, high energy (electronic) ignitions, distributor-less (waste spark) ignition and coil-on-plug ignitions.
Where does the ignition take place in an I.C engine?
The ignition system is one of the most important systems used in the I.C engines. The spark-ignition engine requires some device to ignite the compressed air-fuel mixture. The ignition takes place inside the cylinder at the end of the compression stroke, the ignition system serves this purpose.
What makes up the primary circuit in an ignition system?
An ignition coil consists of two coils of wire wrapped around an iron core, known as the primary winding, or primary coil, and the secondary winding, or secondary coil. The primary circuit consists of the primary coil, the “breaker point” and the car’s batteries.
How does the distributor work in an ignition system?
In addition, while the battery and ignition coil provide the power, the distributor does an important job, that determining precisely where and when that power goes to each spark plug. The distributor decides precisely where and when that power goes to each spark plug.

What happens when you turn off the ignition?
When the vehicle’s ignition system triggering switch turns off the power to the ignition coil, the magnetic field collapses. As it does, the secondary winding captures the collapsing magnetic field from the primary winding and converts it into 15,000 to 25,000 volts.
In addition, while the battery and ignition coil provide the power, the distributor does an important job, that determining precisely where and when that power goes to each spark plug. The distributor decides precisely where and when that power goes to each spark plug.
Newest type of ignition system. Very different from conventional and electronic – coils sit directly on top of the spark plugs, no spark plug wires, and the system is electronic. The third type of ignition system is the distributorless ignition. The spark plugs are fired directly from the coils.
How does a distributorless ignition system work in a car?
Very different from conventional and electronic – coils sit directly on top of the spark plugs, no spark plug wires, and the system is electronic. The third type of ignition system is the distributorless ignition. The spark plugs are fired directly from the coils.
Why do we need an electronic ignition system?
The need for higher mileage, reduced emissions and greater reliability has led to the development of the electronic ignition system. This system still has a distributor, but the breaker points have been replaced with a pickup coil, and there’s an electronic ignition control module.
What happens when there is no spark from the ignition coil?
1 Power. Two positions of the ignition switch provide power to the positive primary post of the ignition coil. 2 Signal. With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. 3 Flow. 4 Open Circuits.
What are the terminals on an ignition coil?
The side terminals of the coil are marked positive (+) and negative (–) and these are where you can measure the resistance of the primary windings. Set the multimeter to the 200-ohm setting and attach the meter’s leads corresponding to the terminal markings, red being positive and black being negative.
What should the resistance of an ignition coil be?
Switch the meter’s resistance range to the 20K-ohm setting and attach the negative (black) meter lead to the center terminal of the coil. The reading here should be 11.00 or better, with 13.49 being about normal. If your coil reads under 11.00, then chances are pretty good that this is the reason you’re not getting any spark or a very weak one.
How do you remove a coil from an ignition coil?
Use a nut driver or a small wrench to loosen the securing nuts on the coil terminals and remove the leads; the positive side of the coil has a condenser lead attached in addition to a positive lead. Then loosen the bottom clamp screw, pull out the center cable that goes to the distributor and remove the coil.
There are three types of ignition system used in modern day vehicles: Battery ignition system (or coil ignition system) Magneto ignition system. Electronic Ignition System.
What does it mean when your ignition key does not turn?
If it will not move, or moves only very slightly, it is likely locked. A locked steering wheel will not allow the ignition to engage. When you move the wheel back and forth, you will feel it stop abruptly as it comes into contact with the steering wheel lock.
What can I use to make my ignition key turn?
Purchase canned air from a local retail or office supply store and insert the straw from the nozzle directly into the key hole. Spray the canned air into the key hole in short spurts.

How does the ignition system work on a car?
The ignition system on your car has to work in perfect concert with the rest of the engine. The goal is to ignite the fuel at exactly the right time so that the expanding gases can do the maximum amount of work. If the ignition system fires at the wrong time, power will fall and gas consumption and emissions can increase.
What are the advantages of an electronic ignition system?
In order to overcome these drawbacks Electronic Ignition system is used. 4.5 ADVANTAGES OF ELECTRONIC IGNITION SYSTEM Following are the advantages of electronic ignition system : (a) Moving parts are absent-so no maintenance. (b) Contact breaker points are absent-so no arcing.
How does a distributorless ignition system coil work?
One of the technologies that enables this long maintenance interval is the distributorless ignition . The coil in this type of system works the same way as the larger, centrally-located coils. The engine control unit controls the transistors that break the ground side of the circuit, which generates the spark.
