Spark plugs have a pretty predictable life cycle, but ignition coils can be harder to track. Here's how to tell if an ignition coil is on its way out.

Spark plugs in good condition Cream or beige color: If the spark plugs are cream or beige in color, clean and dry, this ...

Older cars, specialty performance models, and turbocharged engines may have more frequent spark plug change requirements, perhaps every 50,000 kilometres. Hybrid car engines have spark plugs, too.

Toyota employs a coil-on-plug (COP) ignition system, where each spark plug has its own dedicated ignition coil mounted directly on top. This design not only simplifies the ignition system but also ...

Spark plugs are the heart of your car’s ignition system. If yours are worn out, new ones can dramatically improve your performance. See how to replace them here.

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 ...

Introduced by Cadillac in 1910, ignition points were common right up into the 1970s. This simple system would control when the ignition coil supplied power to the spark plugs, and in the times of ...

While the distributor and coil are some of the most important parts of your ignition system, the spark isn't going anywhere without a distributor cap and rotor, plug wires, and spark plugs.

Primary And Secondary Ignition Systems The secondary ignition system is easy to recognize. It consists of a distributor cap, a rotor, the coil lead, spark plug wires, and the spark plugs.

A multiple-spark CD system like an MSD, Crane, Jacobs, or Mallory can fire a spark plug as many as 8 to 12 times per combustion cycle at idle. Unfortunately, as engine speed increases there is ...

While it cannot cause combustion with just one pulse, it can do so using several 800-picosecond-long pulses. So far, the laser-ignition system hasn't been installed in an actual automobile.

Using these parts, this ignition system distributes timed, high-voltage pulses of electricity to each cylinder; and these pulses, in jumping the gap between the electrodes of the spark plugs ...
