Iran Khodro, which produced the most prevalent car brand in the country - the Paykan, which has been replaced in 2005 by the Samand -, was still the larger with 61% of the market in 2001, while Saipa contributed 33% of Iran’s total production in the same year...

Alcohol Fuel ... Methanol and ethanol Main articles: Methanol fuel, Ethanol fuel Methanol and ethanol can both be derived from fossil fuels, biomass, or perhaps most simply, from carbon dioxide and water... As a fuel, methanol and ethanol both have advantages and disadvantages over fuels such as petrol (gasoline) and diesel fuel... As a compression ignition engine fuel, both alcohols create very little particulates, but their low cetane number means that an ignition improver like glycol must be mixed into the fuel with approx...

Attribution Of Recent Climate Change ... Attribution of recent change to anthropogenic forcing is based on the following facts: The observed change is not consistent with natural variability. Known natural forcings would, if anything, be negative over this period...

Hubbert Peak Theory ... Choosing a particular curve determines a point of maximum production based on discovery rates, production rates and cumulative production. Early in the curve (pre-peak), the production rate increases because of the discovery rate and the addition of infrastructure...

Automotive Industry ... The term automotive industry usually does not include industries dedicated to automobiles after delivery to the customer, such as repair shops and motor fuel filling stations...

Fuel ... Commonly, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived entirely from biological sources, such as tar sands... Fission The most common type of nuclear fuel used by humans is heavy fissile elements that can be made to undergo nuclear fission chain reactions in a nuclear fission reactor; nuclear fuel can refer to the material or to physical objects (for example fuel bundles composed of fuel rods) composed of the fuel material, perhaps mixed with structural, neutron moderating, or neutron reflecting materials... The most common fissile nuclear fuels are 235U and 239Pu, and the actions of mining, refining, purifying, using, and ultimately disposing of these elements together make up the nuclear fuel cycle, which is important for its relevance to nuclear power generation and nuclear weapons...

Automotive Market In The United States ... With the high fuel prices and the world petroleum crisis, the United States has seen its automotive market become more like the European market with fewer large vehicles on the road and more small cars...

Biogas ... In the UK, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel...

Gasification ... The advantage of gasification is that using the syngas is potentially more efficient than direct combustion of the original fuel because it can be combusted at higher temperatures or even in fuel cells, so that the thermodynamic upper limit to the efficiency defined by Carnot's rule is higher or not applicable... Syngas may be burned directly in gas engines, used to produce methanol and hydrogen, or converted via the Fischer-Tropsch process into synthetic fuel... During both world wars especially the Second World War the need of gasification produced fuel reemerged due to the shortage of petroleum...

Future Car Technologies ... With rising gas prices, the future of the automobile is now leaning towards fuel efficiency, energy-savers, hybrid vehicles, battery electric vehicles, and fuel-cell vehicles... A variety of alternative fuel vehicles have been proposed or sold, including electric cars, hydrogen cars, compressed-air cars and liquid nitrogen cars...

Automobile ... Around the world, there were about 806 million cars and light trucks on the road in 2007; the engines of these burn over a billion cubic meters (260 billion US gallons) of petrol/gasoline and diesel fuel yearly...

Automobile Safety ... Improvements in roadway and automobile designs have steadily reduced injury and death rates in all first world countries. Nevertheless, auto collisions are the leading cause of injury-related deaths, an estimated total of 1.2 million in 2004, or 25% of the total from all causes...

Decay Heat ... Decay heat occurs naturally from decay of long-lived radioisotopes that are primordially present from the Earth's beginning. In nuclear reactor engineering, decay heat plays an important role in reactor heat generation during the relatively short time after the reactor has been shut down (see SCRAM), and nuclear chain reactions have been suspended...

Biodiesel ... Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines... Blends Blends of biodiesel and conventional hydrocarbon-based diesel are products most commonly distributed for use in the retail diesel fuel marketplace... Much of the world uses a system known as the "B" factor to state the amount of biodiesel in any fuel mix: 100% biodiesel is referred to as B100, while 20% biodiesel, 80% petrodiesel is labeled B20 5% biodiesel, 95% petrodiesel is labeled B5 2% biodiesel, 98% petrodiesel is labeled B2...

Uranium Nitride ... Uranium mononitride was used as driver fuel for two core loads of the sodium cooled BR-10 reactor in Russia... The property which makes uranium mononitride highly attractive as a nuclear fuel is the combination of a high melting temperature with high thermal conductivity... Increased thermal conductivity results in lower thermal gradients between inner and outer sections of the fuel, potentially allowing for higher operating temperatures and reducing macroscopic restructuring of the fuel, which limits fuel lifetime...

Alternative Fuel Vehicle ... Hybrid electric vehicles such as the Toyota Prius are not actually alternative fuel vehicles, but through advanced technologies in the electric battery and motor/generator, they make a more efficient use of petroleum fuel... Other research and development efforts in alternative forms of power focus on developing all-electric and fuel cell vehicles, and even the stored energy of compressed air... As of 2011 there were more than one billion vehicles in use in the world, compared with around 70 million alternative fuel and advanced technology vehicles that had been sold or converted worldwide as of December 2011, and made up mainly of: 27.1 million flexible-fuel vehicles through December 2011, led by Brazil with 16.3 million, followed by the United States with almost 10 million, Canada (600,000), and Europe, led by Sweden (228,522)...

Second Generation Biofuels ... In comparison, second generation biofuels are made from lignocellulosic biomass or woody crops, agricultural residues or waste, which makes it harder to extract the required fuel... Second generation biofuels can help solve these problems and can supply a larger proportion of our fuel supply sustainably, affordably, and with greater environmental benefits...
