bensiinejä

Bensiini, also known as gasoline or petrol, is a clear to yellowish liquid derived from petroleum. It is primarily used as a fuel for internal combustion engines, particularly in automobiles. Bensiini is a complex mixture of hydrocarbons, with its composition varying depending on the crude oil source and the refining process. Its energy content and volatility are key properties that make it suitable for use in engines.

The refining of crude oil separates it into various fractions based on boiling points. Bensiini is one of these fractions, typically boiling between 40°C and 205°C. Additives are often blended into bensiini to improve its performance and reduce harmful emissions. These additives can include anti-knock agents like ethanol, detergents to keep engines clean, and corrosion inhibitors. The octane rating is a measure of bensiini's resistance to knocking or pinging in an engine, with higher octane ratings indicating greater resistance.

Bensiini is highly flammable and its vapors can form explosive mixtures with air. Due to its widespread use, bensiini is a significant commodity in the global energy market. Its production, distribution, and consumption have substantial economic and environmental implications. Environmental concerns related to bensiini include air pollution from combustion products, such as carbon monoxide and nitrogen oxides, and its contribution to greenhouse gas emissions.
