Bensiinetanool

Bensiinetanool, also known as ethanol gasoline or gasohol, is a fuel additive made by blending gasoline with ethanol. Ethanol is a type of alcohol that can be produced from various organic materials, such as corn, sugarcane, or other biomass. The blending of ethanol with gasoline is done to increase the octane rating of the fuel and to reduce the reliance on fossil fuels.

The most common blend in many countries is E10, which consists of 10% ethanol and 90% gasoline. Higher blends, such as E15 or E85 (85% ethanol), are also available but require specially designed engines or vehicles. The use of bensiinetanool can contribute to a reduction in certain tailpipe emissions, including carbon monoxide and unburned hydrocarbons. However, the overall environmental impact is a subject of ongoing debate, with considerations given to land use for crop production and the energy input required for ethanol production.

Bensiinetanool is used in many internal combustion engines. While most modern vehicles are designed to run on E10 without issue, older vehicles or those with specific fuel system components may not be compatible with higher ethanol blends. The physical properties of ethanol, such as its lower energy density compared to gasoline, mean that vehicles running on higher ethanol blends may experience slightly reduced fuel economy.
