A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...

When I attended technical school studying automotive service technology many years ago, among the first things my instructor taught us was the basic principles of how an engine works. These principles ...

The ignition coil in C1, C2, and early C3 Corvettes is truly an amazing little device. An ignition coil is a type of pulse transformer that multiplies the low voltage received from the battery or ...

Paging through an ignition catalog reveals all sorts of different ignition coils for conventional distributor-type ignition systems. To say it's a mite confusing is an understatement!Just how does an ...

You may have heard about your engine's coil pack but not understood what it does. It's actually a critical component for making your engine run.

Question: I have a 2006 Kia Sedona, and it randomly misfires roughly once for every week of normal driving and once after each carwash. When it happens, I pull over and shut off the car. Then, I turn ...

The ignition coils in your car provide the high voltage electrical current that allows your spark plug to create its spark. These parts are humble looking, and they make use of relatively simple ...

Hinckley Triumph motorcycle owners have been complaining about ignition coil failures since, well, probably since the first Bloor Triumph sputtered off the assembly line. This is Part 1 of this ...

The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

Combustion requires three elements - fuel, air and an ignition source. Air is a no-brainer, being available pretty much wherever drivers are. For most of the history of the automobile we've mainly ...
