where are spark plugs located in a car
Spark plug A spark plug (sometimes, in British English, a sparking plug,[1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a porcelain insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the side, earth, or ground electrode(s).
List of Cars characters Lightning McQueen, often referred to as "McQueen", is the main character in Cars and Cars 3. He is voiced by Owen Wilson. McQueen is not modeled directly after a specific make and model, although his design contains some elements inspired by the Chevrolet Corvette C6. His Corvette lineage is further suggested by the "retro" paint scheme he acquires in Radiator Springs, which resembles that of a Corvette C1.
