Electrical device that fits into the cylinder head of an internal-combustion engine and ignites the gas by means of an electric spark.
Spark-Plug Fouling
A deposit on the electrodes of a spark-plug of essentially non-conducting material that may, but will not necessarily, prevent the plug from operating.
Spark-Plug Whiskering
A deposit of conductive material that tends to form a bridge between the spark-plug electrodes or to a ground, thus shorting out the plug.
