benzínu

Benzínu, also known as gasoline or petrol, is a petroleum-derived fuel commonly used in internal combustion engines. It is primarily composed of a mixture of hydrocarbons, with octane ratings indicating its resistance to knocking or premature detonation during combustion. The refining process of crude oil separates various fractions, with gasoline being one of the lighter, more volatile components.

The primary use of benzínu is as fuel for spark-ignition engines found in automobiles, motorcycles, and small aircraft. Its energy density and ease of storage make it a convenient power source. However, the combustion of benzínu releases pollutants such as carbon monoxide, nitrogen oxides, and unburned hydrocarbons, contributing to air pollution and greenhouse gas emissions.

Over time, various additives have been incorporated into benzínu to improve engine performance, clean engine components, and reduce emissions. Examples include detergents, anti-knock agents like tetraethyllead (largely phased out due to environmental concerns), and ethanol, which is often blended to increase octane and reduce reliance on fossil fuels. The composition and quality of benzínu can vary by region and regulatory standards.
