fuel +

A motor fuel of gasoline blended with 5-25% of amhydrous ethyl alcohol; gasohol: Alcohol fuel is used particularly in European countries.

1. A solid, liquid, or gaseous fuel that is obtained from biological raw material; the conversion is accomplished through thermochemical or biological methods.
2. Gas such as methane or liquid fuel such as ethanol (ethyl alcohol) made from organic waste material, usually by microbial action.
3. A renewable fuel, e.g., biodiesel, biogas, and methane, that is derived from biological matter.

Solid, liquid, or gaseous fuels formed in the ground after millions of years by chemical and physical changes in plant and animal residues under high temperature and pressure.

Oil, natural gas, and coal are examples of fossil fuels.

1. Any material that evolves energy in a chemical or nuclear reaction.
2. Specifically, a material which can be used to provide power for an engine, combustor, power plant, nuclear reactor, etc.
3. Something consumed to produce energy.
4. A material such as wood, coal, gas, or oil burned to produce heat or power.
5. To provide with a combustible substance that provides energy.
6. Fissionable material used in a nuclear reactor.
7. Nutritive material metabolized by a living organism; food.
8. Something that maintains or stimulates an activity or an emotion: "His behavior was fueled by money."
9. Etymology: from Old French fouaille, fuaille, "bundle of firewood"; from Late Latin focalia, plural of focalis, "pertaining to the hearth"; from Latin focus, "hearth"(burning place, fire place).

A device that converts the chemical energy of a fuel directly into electricity and heat withoit combustion, through a process of oxidation.

Fuel cells differ from conventional electrical cells in that the active materials; such as, hydrogen and oxygen, are not contained within the cell, but are supplied from outside.

The total life of a given fuel in all of its uses and forms, including its extraction or generation, transportation, combustion, air emission, byproduct removal, and waste transportation and disposal.

A standard measure of the rate of motor vehicle fuel consumption, expressed as the total distance traveled divided by the amount of gasoline fuel consumed in doing this.

A general statement of this is based on the average mileage traveled per unit of fuel for a class of vehicles; for example, a certain car type in a given model year.

Fuel economy is most often measured by the distance a vehicle can travel with a given volume of fuel. In the U.S., fuel economy is measured in vehicle miles per gallon of fuel. In the European Union, liters per 100 kilometers is the preferred measure.

The efficiency with which a motor vehicle converts energy into movement.

Not necessarily equivalent to fuel economy, in that one vehicle might have better technology and therefore be more efficient than another, but if it is much larger and heavier than the other vehicle, it would have poorer fuel economy.

A dual-chamber furnace in which partial combustion takes place in a primary chamber and combustion is then completed in the secondary chamber.

An array of individual fuel cells connected in a series, for the purpose of increasing electrical current.

An electric-drive vehicle that derives the power for its drive motor(s) from a fuel cell system.
2. A hybrid fuel cell vehicle also derives drive motor power from a supplemental battery or ultracapacitor.

An evaluation of environment impact that considers the effects of obtaining a fuel; such as, from mining coal or harvesting wood; as well as, the more commonly assessed impacts of burning the fuels for useful heat or electricity.

1. Supplied with or powered by fuel.
2. Fed with combustible material.

Someone who, or that which, supplies fuel.

1. The activity of supplying or taking on fuel.
2. Providing a substance such as oil or gas which is used to provide heat or power, usually by going through the process of burning.
