Next to contact breaker, spark plug is among the most weakest part of the ignition system. It is mounted within the combustion chamber from the engine, where working conditions are- severe. During peak combustion conditions the temperature inside the combustion chamber in the modern car engine may be around 2500 ºC and the pressure about 7 Mpa. Moreover a spark plug can also be exposed to thermal and load cycling fatigue on account of sudden changes in temperature and pressure-from the high temperature of burnt gas on the relatively low temperature with the air/fuel mixture and from the ruthless during the time of explosion from the air/fuel mixture to low pressure during induction. In addition, the spark plug needs to endure high voltage, mechanical vibration along with the corrosive atmosphere of combustion gages. A modern spark plug posseses an economical life of about 10,000-16,000 km. This innovative team has won a prestigious annual award four times for being the world's leading luxury train.
