How do breaker points work?
Because of the simplicity of breaker points, it is a good starting point in understanding the switching mechanism that controls the current flow through the coil. The points are made up of a fixed contact point and a movable contact point. The movable point is spring loaded and rides on a 4,6, or 8 lobe cam (depending on the number of cylinders). The points are located inside a distributor. As the engine rotates, the camshaft turns the distributor, which then opens and closes the breaker points as many as 15,000 to 25,000 times a minute. When the points are closed, current is allowed to flow through the ignition coil, thereby building a magnetic field around the windings. When the points are opened, they interrupt that current flow, thereby collapsing the magnetic field and releasing a high voltage surge. This high voltage enters the top of the distributor, where an ignition rotor distributes that voltage through a cap to the right spark plug at the right time. The distributor also contains a condenser that prevents arcing by absorbing excess current when the points open. The difficulty with the breaker point system is that the part that rubs against the cam wears. This wear causes a constant need for adjustment and eventual replacement. In the mid 70’s this problem was corrected through the use of solid state electronics and transistors as switching devices.

What is an ignition system?
The ignition system consists of an ignition coil, distributor, distributor cap, rotor, plug wires and spark plugs. Older systems used a points-and-condenser system in the distributor, newer (as in most we'll ever see anymore) use an ECU, a little brain in a box, to control the spark and make slight changes in ignition timing.
What is the computer that controls the ignition system called?
These days this is all handled by computers. The computer that directly regulates your ignition system is called the ignition module, or ignition control module . There is no maintenance or repair procedure for the module aside from replacement.
How does a distributor work?
As it spins, it distributes the sparks to the individual spark plugs at exactly the right time. It distributes the sparks by taking the powerful spark that came in via the coil wire and sending it through a spinning electrical contact known as the rotor.
What is the coil in a car called?
The ignition coil is the unit that takes your relatively weak battery power and turns it into a spark powerful enough to ignite fuel vapor. Inside a traditional ignition coil are two coils of wire on top of each other. These coils are called windings. One winding is called the primary winding, the other is the secondary. The primary winding gets the juice together to make a spark and the secondary sends it out the door to the distributor.
What does a spark plug do?
At just the right time (thanks to the distributor), when the intake valves have let the right amount of fuel vapor and air into the cylinder, the spark plug makes a nice, blue, hot spark that ignites the mixture and creates combustion.
How many points does a rotor have?
As the rotor spins, it makes contact with a number of points (4, 6, 8 or 12 depending on how many cylinders your engine has) and sends the spark through that point to the plug wire on the other end. Modern distributors have electronic assistance that can do things like alter the ignition timing.
How many contacts are on an ignition coil?

How many types of ignition systems are there?
The 4 Types Of Ignition System And How They Work. By Tsukasa Azuma On Oct 31, 2020. While the automotive industry has achieved drastic mechanical and technological advancement throughout history, there’s one component that all cars with combustible engines have in common: the ignition system.
What is the role of ignition system in a car?
This combustion generates the energy needed to run your car. The ignition system plays a vital role in creating the combustion to run your car. That said, the method by which the spark is created and distributed has greatly improved thanks to technological advancements.
Why are spark plugs removed?
Because each spark plug now has its own dedicated coil that sits right on top for direct firing , high-voltage spark plug wires are completely removed. This increases the system’s efficiency, since spark plug wires introduce greater loss of amperage and voltage, as well as the possibility of contamination and cross-firing between cables if they become greasy or worn.
What is the role of spark plugs in combustion?
To generate such combustion, the ignition system plays a major role: your spark plugs supply the electrical spark that ignites the air and fuel mixture that is fed into the combustion chamber. The ignition system’s spark plug ignites the air-fuel mixture, hence the name “ignition”.
How does ignition work in a car?
In essence, it takes the electrical voltage from the battery, converts it to a much higher voltage, then transfers this electric current to the engine’s combustion chamber and ignites the compressed mixture of fuel and air to create a combustion. This combustion generates the energy needed to run your car.
How many volts does a battery need to ignite?
In other words, the ignition system needs to increase the voltage from the battery’s 12 volts to at least 20,000 volts, which is required to ignite the compressed air and fuel mixture in the combustion chamber to create an energy-generating explosion.
Why is ignition important in compression?
At the same time, the ignition system’s other important role is to ensure that the spark must fire at just just the right moment during the compression stroke in order to maximize the power generated from the ignited air and fuel mixture. In other words, the sufficient voltage must be delivered to the correct cylinder at the precise time and this must be done frequently.
How many types of ignition systems are there?
There are actually more than two types of ignition systems — there are four . These ignition systems include conventional breaker-point ignitions, high energy (electronic) ignitions, distributor-less (waste spark) ignition and coil-on-plug ignitions.
What is a coil in an ignition system?
Ignition System Coil. The coil is a simple device -- essentially a high-voltage transformer made up of two coils of wire. One coil of wire is called the primary coil. Wrapped around it is the secondary coil. The secondary coil normally has hundreds of times more turns of wire than the primary coil.
What is the purpose of ignition in a car?
A vehicle's ignition system creates an electric spark in the engine combustion chamber that ignites the mixture of fuel and air sitting in that chamber.
Where is the coil on a distributorless ignition?
Instead of one main coil, distributorless ignitions have a coil for each spark plug, located directly on the spark plug itself.
Why is timing important in a piston?
And because the length of the stroke and the area of the piston are fixed, the only way to maximize work is by increasing pressure. The timing of the spark is important, and the timing can either be advanced or retarded depending on conditions. The time that the fuel takes to burn is roughly constant.
What happens when a fuel cylinder burns?
When the fuel/air mixture in the cylinder burns, the temperature rises and the fuel is converted to exhaust gas. This transformation causes the pressure in the cylinder to increase dramatically and forces the piston down.
How does a secondary coil work?
The secondary coil normally has hundreds of times more turns of wire than the primary coil. Current flows from the battery through the primary winding of the coil. The primary coil's current can be suddenly disrupted by the breaker points, or by a solid-state device in an electronic ignition.
