It is mounted within the combustion chamber of the engine, where working conditions are- severe. During peak combustion conditions the temperature inside combustion chamber in the modern car engine could possibly be around 2500 ºC along with the pressure about 7 Mpa. Moreover a spark plug can also be encountered with thermal and load cycling fatigue on account of sudden adjustments to temperature and pressure-from the high temperature of burnt gas for the relatively low temperature with the air/fuel mixture and from your underhand during explosion with the air/fuel mixture to low pressure during induction. In addition, the spark plug has got to endure high voltage, mechanical vibration along with the corrosive atmosphere of combustion gages. A modern spark plug comes with an economical life of about 10,000-16,000 km.
