How Plug works

Plugs connected to the voltage magnitude of thousands of volts generated by the ignition coils. Voltage from the ignition coil produces a voltage difference between electrodes in the middle of a spark plug with on the side. Current can not flow because the fuel and air in the gap is an insulator, but the greater the voltage difference, the structure of the gas between the electrodes is changed. At the time the voltage exceeds the dielectric strength than the existing gas, these gases undergo a process of ionization and that had to be insulators, turned into a conductor.






Once this happens, the flow of electrons can flow, and the flow of electrons, the temperature at the spark plug gap rose sharply, to 60,000 K. Very high temperatures makes the ionized gas to expand rapidly, like a small explosion. This is the spark plugs, which in principle is similar to a mini thunder or lightning.

spark plugs

Plugs installed to burn the gasoline that has been compressed by the piston. where is the spark plug? It is a spare parts mounted on the internal combustion engine with the electrode tip in the combustion chamber. how plug works? Spark plugs perform electric spark. At the center of the spark plug electrodes are connected by wires to the ignition coils outside of the spark plug, and with the ground at the bottom of the spark plug, forming a spark gap inside the cylinder. Granted patents for spark plugs separately to Nikola Tesla, Richard Simms, and Robert Bosch. Karl Benz is also one which is considered as the designer of the spark plug.





Internal combustion engines can be divided into the engine with a spark, the spark plugs need to sprinkle a mixture of gasoline and air, and compression engines (diesel engines), with no spark, compressing the fuel and air mixture until there is a spark by itself (so it does not require a spark plug).
