Spark ignition engines typically have ignition systems that develop 20-30 kV for breakdown of the spark plug gap and deliver current pulses in the range of 30-100 mA. These systems are characterized ...

On Point The function of the ignition system is to fire the spark plugs at the correct time, just before the piston hits top dead center (TDC) on the compression stroke, to ignite the fuel/air ...

This animated film "Spark In The Firing Line" provides an in-depth look at the ignition system of modern motor vehicles, focusing on the role of spark plugs in igniting fuel within the combustion ...

An engine compression test kit consists of a pressure gauge and an assortment of hoses and fittings so that the gauge can be connected to the spark plug holes on each of an engine's cylinders. To ...

Some modern vehicles have distributorless ignition systems, which have the spark plug wires connecting each coil pack directly to one or more spark plugs, whereas others are of a coil-on-plug ...

Learning how to change spark plugs is a rite of passage among gearheads, and it's not as daunting as it sounds. Here, we've put together a step-by-step guide to removing and replacing plugs, one ...

The spark plug wire conducts voltage from the ignition system to the terminal on the outside end of the spark plug. Removing the plug wire is necessary to change a spark plug, of course, but it's also ...

Magneto ignition systems and electronic ignition systems are two major types of aircraft ignition systems. Spark plugs are essential components of the ignition system.

Spark plugs are crucial engine components. We prepared the ultimate guide on everything you need to know about testing a spark plug.
