The car's ignition system is very essential to the proper operation of your car's engine, actually an important part of the overall engine system. Keeping it well maintained can help you keep your vehicle on the road longer. But what is the car's ignition system, anyway? What are its components and how does it works? Here it goes. The car's ignition system provides for the timely burning of the fuel mixture within the engine. However, not all engine types need an ignition system. A diesel engine for instance, relies on compression-ignition, that is, the rise in temperature that accompanies the rise in pressure within the cylinder is enough to ignite the fuel spontaneously. But all conventional petrol engines on the other hand, require an ignition system.

For the ignition system to be able to function at its best, it needs components which have its own role to portray. It includes the spark plugs, the ignition wires and coil, and the distributor. The ignition system produces an electrical charge and transmits it to the spark plugs through the ignition wires. The charge first flows to a distributor. The distributor rotates via a gear on the camshaft and triggers the ignition. The coil then fires, sending its power back to the distributor through the coil wire. The distributor has one ignition wire that goes in the center and four, six, or eight wires (depending on the number of cylinders) coming out of it. These wires send a charge to the spark plugs individually. The process is exactly timed so the engine runs smoothly.

On older distributor-type ignition systems, there is another mechanism on the bottom half of the distributor controlling the timing of the high-voltage electric pulses. This mechanism includes the breaker point or contact point that opens and closes to barge in the battery current to the coil. But since spark timing is very critical to the engine's performance, modern distributor systems have substituted the said mechanism with a transistor controlled by the engine control unit computer or ECU. On the other hand, many new automobiles feature a distributorless ignition system. The distributorless ignition system, of course, does not make use of the distributor, rotor or cap; instead the engine management computer tells the coil when to fire.

So if lately, you have noticed that your Saturn engine has been running poorly, perhaps some of your ignition system components are damaged. If in case you found out that it is your Saturn distributor that is causing the problem, then replacing it necessary.
