Start Me Up (Ignition Systems)
June 23, 2024
When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades. You have spark plugs that require enough power so a spark can jump across a gap at its tip. Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing.
The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off. That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers. Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers.
The next evolution came in the 80's when the distributor was replaced with a couple of sensors which talked to a computer. This "DIS" (distributor-less automotive ignition system) was a big advance. Plus, it didn't use just one ignition coil for all the cylinders. It had coil "packs" that each provided spark to two cylinders. That way, the voltage could be boosted even higher, to 30,000 volts, which helped engines be able to ignite a leaner fuel/air mixture.
Recently have come even more improvements. Now instead of coil packs, there's a coil that's attached to each spark plug. No more spark plug wires means less maintenance. Plus, a stronger, hotter spark of 50,000 volts can make an engine more reliable, increase fuel economy and reduce emissions.
No matter what ignition system your vehicle uses, your vehicle service facility has a staff of technicians trained to work on the latest technology. Make sure to have your vehicle maintained regularly so you can take full advantage of these modern engineering marvels.

When asked, most people think they are good at multi-tasking. Scientific studies, however, reveal that only around 2% of the population can truly demonstrate the capacity to effectively multi-task. For the rest of us who are not so biologically wired, no amount of practice can increase our effect... More
