Spark plug is an automobile device, which is used in internal combustion engines. It ignites the compact fuel mixture in the combustion chamber of internal combustion (IC) engine. The purpose of spark plug is to create the right amount of combustion gap and to transfer electric energy from the ignition system to the compact fuel inside the combustion chamber. Heat should be transfer from the insulator to the metallic shell and then into the combustion chamber thanks to the high combustion temperature that is applied to the insulator and central electrode. Spark plug have different parts some of the major parts are insulator, spark plug terminal, central electrode, ground electrode, spark plug gap, outer metallic body.
Spark plug is a small device but it plays very crucial role in vehicles, to function it on daily basis. Spark plug must form a fit condition that to get assembled in the main combustion chamber of the AL-31Fp engine with the limited life of 1000 flying hours. Highest weight of the part is 0.28 kg max. The increasing production and adoption of vehicles globally are augmenting the growth of Spark Plug market. The usage of spark plugs in automobile vehicles is essential and thus it makes the spark plug market grow in the years and is expected to sustain the growth during the forecast period.
Sparks contain some of the possible concerns such as difficulty in starting vehicles, roughly idle due to misfiring, loss of power, poor fuel economy, and increased emission, because of this issues people can get converted towards the electric vehicles and it may hinder the growth of spark plug market. The concerns related to the spark plug can be solved, the spark plug can be replaced, it likely to give some benefits such as, enhance power, increased the fuel economy and decrease the emission, vehicle starts working smooth and it also reduced the risk of catalytic converter failure.
