Flexible-fuel vehicleA flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.
Energy Independence and Security Act of 2007The Energy Independence and Security Act of 2007 (Pub.L. 110-140), originally named the Clean Energy Act of 2007, is an Act of Congress concerning the energy policy of the United States. As part of the Democratic Party's100-Hour Plan during the 110th Congress, it was introduced in the United States House of Representatives by Representative Nick Rahall of West Virginia, along with 198 cosponsors.
Internal combustion engineAn internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to components of the engine.
History of ethanol fuel in BrazilThe history of ethanol fuel in Brazil dates from the 1970s and relates to Brazil's sugarcane-based ethanol fuel program, which allowed the country to become the world's second largest producer of ethanol, and the world's largest exporter.
GasolineLiquid fuel derived from petroleumGasoline in a glass jarGasoline (North American English) or petrol (in other English-speaking countries) is a petrochemical product, a transparent, yellowish and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. It is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives.

Many processes in chemistry can be impeded by the presence of water; therefore, it is important that water-free reagents and techniques are used. In practice, however, it is very difficult to achieve perfect dryness; anhydrous compounds gradually absorb water from the atmosphere so they must be stored carefully. Substances that contain water or its constituent elements are called hydrates.
CarA car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, seat 1-8 people, have four wheels, and mainly transport people rather than cargo. There are over 1.6 billion cars in use worldwide as of 2025.
British thermal unitThe British thermal unit (Btu) is a measure of heat, which is a form of energy. It was originally defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units. The SI unit for energy is the joule (J); one Btu equals about 1,055 J (varying within the range of 1,054–1,060 J depending on the specific definition of Btu; see below).HydrateIn chemistry, a hydrate is a substance that contains water or its constituent elements. The chemical state of the water varies widely between different classes of hydrates, some of which were so labeled before their chemical structure was understood.
Light truckLight truck or light-duty truck is a US classification for vehicles with a gross vehicle weight up to 8,500 pounds (3,860 kg) and a payload capacity up to 4,000 pounds (1,814 kg). Similar goods vehicle classes in the European Union, Asia and Africa are termed light commercial vehicles and are limited to a gross vehicle weight of up to 3,500 kg (7,720 pounds). Australia and New Zealand are limited to a gross vehicle weight of up to 4,500 kg (9,920 pounds).*As an Amazon Associate I earn from qualifying purchases.
