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. In the era of sixth century three kinds of drama were written like Tragedy, Comedy and Satire. Tragedy generally depicts the tale of mythological incidents. Where from the drama starts that's no matter though the ending with the drama should be a pathetic scene. Comedy also associated with the mythological subjects however the presentation of the drama come in a humorous way. Every audience left for home with joyful mood.
