Internal combustion gasoline engines run on a mixture of gasoline and air. The ideal
mixture is 14.7 parts of air to one part of gasoline (by weight). Since gas weighs much more
than air， we are talking about a whole lot of air and a tiny bit of gas. One part of gas that is
completely vaporized into 14.7 parts of air can produce tremendous power when ignited inside an
engine.
