What is Octane numbering of Petrol?
- Octane number, also called Antiknock Rating, a measure of the ability of a fuel to resist knocking when ignited in a mixture with air in the cylinder of an internal-combustion engine.
- Engine knock is a tapping, pinging sound that gets louder and more obnoxious as we accelerate.
- The octane number is determined by comparing, under standard conditions, the knock intensity of the fuel with that of blends of two reference fuels: iso-octane, which resists knocking, and heptane, which knocks readily.
- The octane number is the percentage by volume of iso-octane in the iso-octane–heptane mixture that matches the fuel being tested in a standard test engine.
