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.

Your gasoline engine goes through some exhausting work. Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve. Did you know it's a ser... More

We've all heard that expression, "That's a non starter." When it comes to your vehicle, that's not music to a driver's ears. That sickening sound when you start the ignition and instead of hearing the engine crank, you hear it slowly turn over and your dash lights go dim. There can be many reaso... More

Its always more comfortable in your vehicle when you can control temperature and humidity in the cabin. Air conditioning, which is standard on most newer vehicles, is a vital part of that comfort, and a key component of that system is the condenser. The condenser converts the refrigerant gas into...
