Petroleum is the most common source of fuel for modern internal combustion
It contains two important elements: carbon and hydrogen.
elements are mixed in proportions such that allow them to burn freely in air
and liberate heat energy.
Petroleum contains a tremendous amount of
potential energy. In comparison to dynamite, a gallon of gasoline has six
times as much potential energy. Gasoline is the most widely used petroleum-
based engine fuel.
Two advantages of the use of gasoline are a better rate of burning and easy
vaporization to give quick starting in cold weather.
purity, and antiknock quality (octane rating). In this lesson, the function
task will center on the specific characteristics of gasoline.
