What makes a car ignition start?

Answer 1

Internal Combustion Engine

An explosive fuel such as gasoline is sprayed into a series of chambers as a very fine mist. A spark plug emits a tiny burst of electricity, which causes the atomized gasoline to explode. This explosion pushes down a series of valves and pistons which ultimately turn the engine's main crankshaft. The crankshaft then provides the force for the wheels to propel the car forward through a series of gears. As long as the spark plugs are igniting the gasoline vapors, the engine will continue to provide power. Once the electricity is turned off, however, the entire process quickly stops.
