Spark ignition is a system used in an internal combustion engine, such as a gasoline engine, to ignite a mixture of air and fuel inside the combustion chamber. Ignition of fuel is generated by a spark plug.
[edit] How it Works
The process involves the use of a spark plug, an electrical field in the form of a coil or magneto. This field produces thousands of volts then collapses via a timed circuit. What is left is a surge of current that travels through a wire and ends at a spark plug inside the chamber. As the surge or charge of electricity tries to jump over a gap at the tip of the spark plug, a metered mixture of air and fuel has already been completely compressed inside the combustion chamber. The result is an explosion or combustion that generates enough power to turn the reciprocating mass inside the engine.[1]
