The British Glass entry features its three-year programme to facilitate collaboration between glass manufacturers and government to create a decarbonisation action plan – setting out the sectors’ priorities for energy efficiency and decarbonisation in areas such as research and development, technology implementation, energy infrastructure, recycling, skills and funding. In April of this year all ten of the UK’s large-scale glass manufacturers signed up to the voluntary action plan. Next to contact breaker, spark plug has become the weakest section of the ignition system. 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.
