Illuminating the Engine: A Comprehensive Guide to Spark Plugs
What is a Spark Plug? Spark Plug is a device that is used to ignite the air-fuel mixture in the engine cylinder of an internal combustion engine. They are generally used in petrol engines or engine that runs on Natural gas. For the combustion of the fuel, we need a spark to initiate the combustion process in a gasoline engine ( Petrol engine ). A good spark plug produces sparks at the correct timing making the combustion of air-fuel mixture efficient and this improves the working of our vehicle. Requirements of a Good Spark Plug It must be reliable at high voltage transmission i.e. up to 40,000 V. It must have good insulation capability even at temperatures of 1000 degree Celsius, and prevent arcing and flashover. It must possess resistance to thermal shock (Hot exhaust gases-cold intake mixtures) It must make pressure-tight and gas-tight sealing with the combustion chamber. It must be capable to resist oscillating pressures up to approx. 100 bar. It should have high mechanical st...
