Spark 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 is a seemingly simple device, although it is tasked with a couple of different but critical jobs.
Global spark plug market is expected to reach $2,904 million by 2022, growing at a CAGR of 4.2% during the forecast period 2014 - 2022. Spark plug is an electrical device threaded into the cylinder of spark ignition engine, which produces spark at the required time to ignite the combustible air-fuel mixture in the cylinder bore. The device comprises shell, resistance, electrodes, and insulator. During the engine operation, when high tension current flows through the center electrodes, it ionizes the gas present between the electrode gaps, producing spark.
A spark plug or a sparking plug is used to deliver electric current during the combustion process to produce spark. It has a metal threaded shell and finds its usage in numerous applications such as furnaces, marine, ignition and outdoor applications among others. It is an electrical device threaded into the cylinder of spark ignition engine.
Spark Plug market stood is forecast to exhibiting a CAGR of more than 11% over the next five years. Growing automobile production and sales coupled with increasing preference for dual-fuel option passenger cars and various ongoing and upcoming technological advancements are expected to boost the sales of automotive spark plugs in India over the coming years. Spark Plugs are the device to transfer the electric current from ignition system to combustion chamber of a vehicle. Stringent regulations & norms by government regarding emissions & fuel efficiency and growth of automotive industries are driving the market for spark plugs.
