Why Can Electric Sparks Ignite Gasoline

1. An electric spark is generated by high-voltage currents passing through the positive and negative terminals of the spark plug.

2. To be precise, it’s the combustion of a mixture of gasoline and air, not just gasoline alone.

3. A mixture of air and gasoline, particularly in the readily combustible ratio of 14.7 parts air to 1 part gasoline, ignites effortlessly.
