	The [[voltage]] in the ignition system must be high enough to create a spark across the spark plug gap (see figure 2), much like a bolt of lightning traveling from the clouds to the Earth.

Spark plugs are an important part of gasoline engines, but not a part of [[diesel]] engines, since diesel is ignited by [[compression ignition]] instead. In figure 2 below note that the timing of when the spark plug fires is very important. The [[combustion]] needs to happen at a precise time, combusting too early (usually because of ignition from compression) leads to [[engine knocking]].
