What is the work of spark plug in car?
What do spark plugs do? Small but mighty, the spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. By putting the engine’s pistons in motion, your car can power up, stay powered up and produce a smooth burn of the compressed air-fuel mixture.
What is the spark plug system?
Spark plug, also called Sparking Plug, device that fits into the cylinder head of an internal-combustion engine and carries two electrodes separated by an air gap, across which current from a high-tension ignition system discharges, to form a spark for igniting the air–fuel mixture.
What are the parts of a spark plug called?
A spark plug is made of a center electrode, an insulator, a metal casing or shell, and a side electrode (also called a ground electrode). The center electrode is a thick metal wire that lies lengthwise within the plug and conducts electricity from the ignition cable hooked to one end of the plug to the electrode gap at the other end.
What does a spark plug look like?
Look for light grey or tan metal on a good spark plug. A spark plug that is not damaged will appear light grey or possibly tan. There should be no buildup on the sparking surface of the plug. If you purchased new spark plugs, their colors should be fairly similar. A good spark plug will not need to be replaced.
What are the requirements of a spark plug?
In order to do this task effectively a spark plug must fulfill following requirements: 1) It must provide a gap or spacing and be located in the combustion chamber such that it allows smooth engine operation over the entire operating range from idling to wide open throttle running with maximum fuel economy.
What is the purpose of spark plugs in an engine?
The spark plug is the device that causes the fuel/air mixture in the cylinder to burn. All internal combustion engines have a spark plug, or in the case of diesel engines, a glow plug, to initiate combustion in the engine. Spark plugs in a gasoline engine have an additional purpose of removing heat from the combustion cylinder.
