What Are Spark Plugs?

Spark plugs are an essential part of any gasoline engine, serving as the interface between the piston and the combustion chamber. At their core, spark plugs are comprised of two primary components: a metal rod known as a "center electrode", and a ceramic insulator that separates this rod from the metal of the housing. This electrode is attached to a high-voltage electrical current that brings it in contact with a ground electrode, ultimately causing the center electrode to spark against the fuel/air mixture in the combustion chamber.

When this happens, an explosion is created that drives the piston downwards and powers the engine. Thanks to their simple but effective design, spark plugs have played a vital role in transportation for hundreds of years. Whether you're driving along a highway in a modern car or riding an old moped down a cobblestone street, your vehicle couldn't run without these critical components. So the next time you fire up your engine and head out on your journey, be sure to thank your spark plugs for getting you there!

How Does Spark Plug Work?

The spark plug is an essential component of the modern internal combustion engine, serving as a crucial junction between the cylinder and the ignition system. At its core, a spark plug consists of a central electrode surrounded by an insulating material. When a current flows from the ignition coil to this electrode, it ignites a mixture of fuel and air in the cylinder, generating a powerful spark that starts the combustion process.

In addition to creating this electrical arc, the spark plug has several other important functions. It provides shielding against high compression and heat from the combustion cycle, prevents blowouts from pressure differentials in the cylinder, and regulates incoming fuel so that it is timed properly with each stroke. As such, it is clear that the spark plug plays a critical role in ensuring efficient engine performance.
