By understanding the role of your spark plugs and recognizing the signs of worn spark plugs, you’ll be rewarded with a boost in fuel economy and a smooth ride.

 

Inside the engine, valves fill the cylinders with an air/fuel mixture which is highly explosive when exposed to a source of ignition. The pistons compress the air/fuel mixture, increasing the amount of potential energy. At the peak of compression, a spark plug creates an arc of electricity lasting approximately 1/1000 of a second, igniting the air/fuel mixture inside the combustion chamber. This creates an explosion that forces the piston back down to its starting position. The crankshaft turns this energy into rotational motion, and your car moves forward.

 

The Purpose of Spark Plugs

The basic operation of an internal combustion engine, which describes your car's gasoline motor, is not particularly complex. The motor first mixes gasoline and air in small quantities and then ignites the mixture inside a cylinder with an electrical spark.
