A diversity of machine fuels are available.
A incongruity of fuel types are available for cars. Some are fictional from crude oil products however others are petroleum alternatives that were developed whereas of soaring Gauze and diesel prices. A handful are life explored and aren't as widely available on nowadays's marketplace.
Ethanol
Ethanol is a fuel prepared from plant materials, Frequently wheat or corn. As such, it is a renewable fuel source for cars and is considered an choice for environmentally benevolent vehicles. Most now Gauze blends, that are purchased at usual Gauze stations, encompass between 7 and 10 percent ethanol. Some cars, including many racing cars used in the Indy 500, are fueled by 100 percent ethanol. E85 is a blend of 85 percent ethanol and 15 percent gasoline. Many cars, currently in production, are compatible with E85, including the Chrysler Sebring, Dodge Dakota and Ford Crown Victoria.
Propane
Propane, also called liquefied petroleum gas, is a byproduct of the petroleum industry and is a gas, not a liquid. Propane is considered safer than gasoline because propane vehicles are equipped with built-in shut-off valves in case of a propane leak. Since gas prices started rising in the 1980s, it has been an alternative to gasoline.
Natural Gas
Natural gas is largely used for tasks like heating homes, but some cars run on natural gas. Methane is the main ingredient in natural gas. The gas is formed underground by decomposing plant and animal matter. Natural gas burns clean, is easy on a car's engine and is smokeless, making it a cleaner fuel option. It is difficult to keep in supply because it needs to be compressed up to 200 times atmospheric pressure.
Liquefied natural gas also is available but isn't as readily available since it needs to be liquefied in a liquefying station on-site at each individual gas station.
Methanol, a byproduct of natural gas, can be used to fuel vehicles but a network of fueling stations has not been set up for it.
Blends of biodiesel and petroleum can be used to fuel some diesel vehicles.
Diesel
Diesel is a crude oil product that has been used in engines since the late 19th century.Biodiesel
Biodiesel is typically made from vegetable oils like corn and canola. Because it is from a plant source it is considered a renewable resource and is one of the leading fuel alternatives considered by environmentalists. Biodiesel also can be derived from used cooking oil or animal fat.Crude oil goes through a process that includes distillation to produce diesel. Both gasoline and diesel are made from crude oil, but diesel is heavier, evaporates slower and has an oilier texture to it.
Gasoline
Gasoline is the most common fuel used in cars. It is made from crude oil and is distilled like diesel but goes through further processing to refine it. Gasoline started being used as fuel for cars in the early 20th century. Because there is only a finite amount of crude oil available, gas prices have started to rise and both consumers and engineers are looking at alternative fuels to crude oil products.
