Since ignition systems are made up of a number of different components, a lot of different moving parts had to come together before they could be developed. One of the earliest examples of some of the major principles utilized by spark-ignition systems dates back to , when Alessandro Volta built a toy electric pistol that used an electric spark to ignite a mixture of hydrogen and air to shoot a cork.
Although Alessandro Volta demonstrated how an electric spark could be used to drive what essentially amounted to a piston, two major components had to be invented before the ignition system could be developed.
The first component was the magneto, which is a device that uses magnets to generate an electric current. Another watershed moment in the history of the ignition system was invention of the spark plug in This component, which is ubiquitous in modern spark-ignited internal combustion engines, was developed by Belgian engineer Etienne Lenoir for his gasoline engine. At around the turn of the century, Rudolph Diesel developed the Diesel cycle. This resulted in the development of a completely different type of ignition system that sometimes utilizes components like glow plugs to assist in ignition.
In the early years of the 20th century, basic magneto ignition systems were developed into switchable systems. These systems were manually switchable from using replaceable dry cell batteries to start an engine and run it at low speeds to using magneto ignition at higher speeds.
The next major development in the history of the ignition system came in , when Cadillac introduced an engine that utilized a battery and coil type ignition. This system had all of the same basic parts that were used for over half a century, including a battery-operated coil, a capacitor, points, and a distributor.
Like modern ignition systems, the coil generated the current necessary to induce a spark, the points acted as the switch to trigger the coil, and the distributor sent the spark to the proper cylinder at the necessary time. Modern ignition systems use electronic ignition instead of mechanical devices like points.

Most cars have a point gap of about 0. Some are set higher or lower, so check your manual to be sure. To measure the point gap, you need a set of feeler gauges. Adjusting the point gap is a simple process, but it takes some practice to get the hang of doing it properly. First, make sure the rubbing block is on the high point of one of the cam lobes. If it isn't, you will have to turn the engine a little bit in order to turn the cam.
Once you have the rubbing block on top of a lobe, you can measure the point gap. Loosen the screw that holds the stationary point bracket to the base plate. Not completely, just enough so that you can move the bracket by inserting a screwdriver tip and twisting it Adjustment is a matter of trial and error. Move the stationary point out a bit if it was too close, tighten the holding screw not too tight , and measure the gap.
If it still isn't right, try again. The feeler gauge should have a light drag when the points are properly adjusted. This is where practice and patience come in handy. The points must stay closed long enough to allow the coil's primary current to reach an acceptable value and open long enough to discharge and produce a spark.
Many mechanics like to check the dwell measurement with a dwell meter after setting the points. There are some who say you don't have to. That someplace takes the spark and sends it out to the spark plugs, and that someplace is the distributor.
The distributor is basically a very precise spinner. 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. The rotor spins because it's connected directly to the shaft of the distributor. 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.
