Energy density is the amount of energy stored in a given system or region of space per unit volume or mass. It therefore has units of energy per length cubed or energy per mass. Gasoline has an energy density of about 45 megajoules per kilogram (MJ/kg).
Gasoline is a mixture of the lighter liquid hydrocarbons used chiefly as a fuel for internal-combustion engines. It is produced by the incomplete refinement of petroleum; by condensation or adsorption from natural gas; by thermal or catalytic decomposition of petroleum or its fractions; by the hydrogenation of producer gas or coal; or by the polymerization of hydrocarbons of lower molecular weight.
Gasoline is one of the most important fuels used in the transportation industry. Most gasoline is used in engines that move automobiles and light trucks. Gasoline engines also power other vehicles and machines, including airplanes (aviation), motorboats, tractors, and lawn mowers.
