bensiiniäöljyä

Bensiiniäöljyä is a Finnish term that translates to "gasoline oil" or more commonly, gasoline. It refers to a highly flammable liquid mixture of hydrocarbons derived from petroleum. Gasoline is primarily used as fuel in internal combustion engines, particularly in automobiles. Its composition varies depending on the refinery and desired performance characteristics, but it typically consists of hydrocarbons with carbon numbers ranging from 4 to 12.

The octane rating is a key measure of gasoline's performance, indicating its resistance to knocking or pinging, which is uncontrolled combustion within the engine cylinder. Higher octane fuels are generally used in higher-compression engines to prevent premature detonation. Additives are often blended into gasoline to improve its properties, such as detergents to keep the engine clean, anti-corrosion agents, and stabilizers to prevent fuel degradation.

Gasoline is produced through the fractional distillation of crude oil. The lighter fractions, which have lower boiling points, are separated and further processed through processes like catalytic cracking and reforming to produce the complex mixture that makes up gasoline. Its production, distribution, and sale are subject to stringent regulations due to its flammability and environmental impact. While gasoline has been the dominant fuel for transportation for over a century, its use is increasingly being scrutinized due to concerns about air pollution and climate change, leading to the development and adoption of alternative fuels and vehicle technologies.
