What Does a Spark Plug Do?

A spark plug is a device that uses a small bolt of electricity to ignite the fuel and air mixture in the car’s engine, creating the combustion that moves the pistons and your vehicle moving. A spark plug is installed in one cylinder of each engine. It can start the engine and also drive the vehicle.

The portion of the plug that sticks out from the engine is connected to the vehicle’s ignition system, which must provide a specific amount of electric current to generate a spark inside each of the engine’s cylinders.

-The opposite and the spark plug has two exposed electrodes that are located inside the cylinder. The electrical current from the ignition system travels to the plug’s center electrode. A high-voltage spark jumps a small gap to reach the second electrode.

-That spark ignites the fuel-air mixture inside the engine cylinder. Each time a spark is created, a small explosion occurs inside the cylinder that pushes down against the top of the piston. The type of engine tells you how many spark plugs you need. If your vehicle has four cylinder, it has four pistons, six cylinder, six pistons, etc. each served by an individual plug.

 

 

Why You Need To Replace Your Spark Plugs

Most spark plugs have a lengthy life and can be changed on schedule with routine maintenance. It’s beneficial to keep healthy plugs and wires to help ensure they fire on time and keep the engine running smoothly. Faulty or worn-out spark  plugs prevent the synchronized combustion that makes smooth engine operation.

Why Do Spark Plugs Go Bad?

Spark plug are usually not visible so they are not on the driver’s mind. It worsens with repeated heating. The spark plug tips chamber may overheat in the accumulation or cooling system of the combustion group.

Importance of Spark Plugs

Unless you own an electric vehicle, spark plugs will be a necessary component of your vehicle. An internal combustion engine, or ice for short, is installed In your car. The presence of a spark is required for these combustion components.

Spark plugs are an important aspect of the operation of your car engine since they are responsible for producing combustion during both ignition and as the engine goes through combustion cycles as you drive. Your engine won’t run at maximum combustion if your spark plugs aren’t working properly.
