How does a spark plug work in a Nissan?

Each spark plug works hard to kindle the air-fuel mix in the combustion chamber which drives your automobile. Your typical Nissan spark plug generates an electrical spark over a set gap on your plug, and once that happens, the delta is complete, so the boom can happen within your engine.

What are the spark plugs on a Saturn?

The Saturn car has four spark plugs, one for each cylinder. Unlike other vehicles, however, the Saturn car uses a coil-on-plug setup instead of spark plug wires, where each spark plug has a separate ignition coil that amps up the battery voltage to the necessary power required to fire the spark plug.

Why are spark plugs so hard to fire?

Used spark plugs are hard to fire as the gaps are worn out, and insulation properties of the ceramic is compromised by solid combustion deposits and old fuel saturation. This robs available voltage at the spark plug gap, as it “leaks” through the low resistance carbon deposits to the ground, resulting in a weak spark.

How does the potential of a spark relate to the spark plug?

1) Potential of the ignition system – Spark Voltage (sometimes explained as Voltage potential or electrical pressure) corresponds with the distance that spark can cross at given air pressure and enviroment (concentration of the A/F (Air/Fuel) mixture etc… between the spark plug gap (center electrode and ground electrode).
