Spark Plug

A spark plug is essential for the engine to run, it must have the proper mix of fuel, compression, and a spark. When the plugs are not firing they are used for ionization of cylinders. The spark plug goes all the way back to 1860 when it was first used to spark a gas engine. It is composed by a shell and insulator, which is inserted into the combustion chamber where it is sealed into pressure and temperature that are extreme.

The spark plugs main job is to create spark to fire up the combustible mix. There is a gas that ionizes and allows the current to travel to the gap. Spark plugs need a voltage of minimum 12,000 to 25,000 to work properly, and it can even surpass 25,000 with no problem. The pressure and intense heat causes a small explosion to fire up the vehicle.

The spark plug is made up of a shell, insulator, and conductor. The terminal is part of the spark plug which connects to the ignition system, but it can vary depending on the way you use it. The insulator comes next which is the part that is most important as it provides mechanical support. The ribs are there to prevent electricity from entering the metal case, and the seals help the plug cover up the combustion chamber to make sure there is no leakage.

The plugs also come in many sizes ranging from 10 mm to 18mm. The steel shell is also very effective when it comes to transfer heat from the plug to the cylinder head. The regular spark plug comes with a copper core and metal terminal for the steel shell. And although the variations of plugs have changed, they all try to accomplish longevity as well as perfect ignition.

Issues with a spark plug can lead to a lot of problems, like the vehicle being less efficient on gas, stalling, and maybe even damage some components. Replacing the bad plug can restore the vehicle to its original condition.
