The function of a spark plug is to produce a spark at the required time to ignite the combustible mixture. The plug is connected to the high voltage generated by an ignition coil or magneto. As current flows from the coil, a voltage develops between the central and side electrodes.
Spark plugs are relatively simple to replace. Learn how spark plugs function and get tips on how to replace them in this article.
Whether you’re searching for how to read spark plugs for tuning, how to read spark plugs for rich or lean conditions, or for any purpose, read to the end, when reading spark plugs, you have to locate the spark plugs and remove the ignition lead cables or the ignition coils.
What Spark Plugs Do and How They Work. Spark plugs are small electrical devices used in some internal combustion engines and are prevalent in the function of your vehicle's engine. They feature an insulated electrode in the center, insulated wire, and an ignition coil or magneto circuit with a grounded terminal.
A spark plug is used as a source of ignition, as the "spark" in its name implies. It is a key component of internal combustion engines and its primary function is to ignite a fuel/air mixture within the combustion chamber of a car, or other system. Figure 1 shows plugs, the spark travels across the gap on the left side of the spark plug.
Nov 23, 2015 · Your spark plugs are among the most important of these, and you have several of them (one per cylinder). The job of your spark plugs. Spark plugs have a very simple yet essential job. They provide the spark necessary to ignite gasoline in the combustion chamber.
Spark Plug Basics. The primary function of the spark plug is to ignite the air-fuel mixture within the combustion chamber under any operating condition. Spark plugs must provide a path and a location for electrical energy from the ignition coil to create a spark used to ignite the air-fuel mixture.
