A spark plug is an ignition system component used in gasoline-powered engines. While diesel engines use compression ignition, gasoline engines require a source of ignition for every combustion chamber. Producing an electric spark at certain moments, spark plugs ensure higher efficiency of the combustion process than the diesel engine does. All this results in a lower emissions level and higher output, which makes gasoline engines more favorable. However, while operating, spark plugs are constantly contaminated by the by-products of combustion, so they may wear out from those severe conditions that they work under.
