Octane octane number
Octane Number
Octane number is a measure of the performance of a fuel in an internal combustion engine. It is a measure of the fuel’s ability to resist detonation (knocking/pinging) when the fuel is used in an engine. The higher the octane number the less likely the fuel will detonate, although ......
