A motor fuel is a fuel that is used to provide power to the engine of motor vehicles — typically a heat engine that produces thermal energy via oxidative combustion of liquid or gaseous fuel and then converts the heat into mechanical energy through reciprocating pistons or gas turbines.
Currently, the majority of motor vehicles worldwide are propelled by internal combustion engines powered by petroleum-based fossil fuels such as gasoline, diesel or autogas. Other fuel types include ethanol, biodiesel, biogasoline, propane, compressed natural gas (CNG) and hydrogen (either using fuel cells or hydrogen combustion). There are also cars that use a hybrid drivetrain of different power sources. The use of synthetic alternative fuels (especially renewable biofuels) is increasing, especially in Europe,[1] as well as increasing mass adoption of battery electric vehicles (which are powered by battery-stored electricity instead of fuels).
Before deciding on a particular fuel type, some factors should be considered:[2]
