octane

 

[ ˈɒk.teɪn ]

Noun
Context #1 | Noun

chemistry

Octane is a hydrocarbon and a member of the alkane series with the chemical formula C8H18. It is a colorless gas at room temperature and atmospheric pressure but is found as a liquid under higher pressures. Octane is best known as a significant component of gasoline and is important because it determines the fuel's ability to resist knocking when burned in internal combustion engines. Its performance is measured by the octane rating, with higher ratings indicating a better ability to resist engine knocking.

Synonyms

heptadecane, isooctane

Examples of usage

  • The octane rating of this fuel is high.
  • You should use premium octane for your sports car.
  • Engine performance improves with the right octane level.
Context #2 | Noun

fuel

In the context of fuel, octane refers to a standard measure of the performance of an engine or aviation fuel. It is crucial for a vehicle's performance, influencing fuel efficiency and engine smoothness. Different octane levels are designed for various types of engines, and selecting the appropriate octane is essential for optimal engine functionality.

Synonyms

fuel grade, fuel type

Examples of usage

  • Lower octane fuels can lead to engine knocking.
  • Many cars require high octane fuel for optimal performance.
  • Check the octane level recommended for your vehicle.

Word origin

The term 'octane' originates from the Latin word 'octo,' meaning 'eight,' which refers to the eight carbon atoms in its chain. In the late 19th century, octane was first identified as a distinct component of petroleum. In the early 20th century, octane became a crucial concept in the study of gasoline performance. Researchers developed the octane rating system as a measure of fuel's ability to withstand premature ignition. The introduction of isooctane as a standard reference point further solidified octane's importance in fuel science. Over the decades, the correlation between octane ratings and engine efficiency has led to advancements in fuel formulations, resulting in more environmentally friendly and high-performance fuels.
