octane number
I think it might be 'octane number'
Regular unleaded fuel is 87 octane. High octane fuel is any fuel higher than regular. 89 and 91 octane being the most common the consumer can buy. High octane fuel is not needed in most cars and is a waste of money if your car does not need it. It provides no benefit whatsoever in a vehicle designed to run on Regular. Octane is only a measure of how well the fuel prevents pre-detonation in a high compression engine.
The octane number is a measure of performance of a fuel. It is measured relative to pure isooctane which is given an arbitrary value of 100. It is possible for fuels to have an octane number higher than 100. The higher the octane number the more compression it takes for the fuel to detonate. Higher octane fuel is used usually in high performance vehicles where the engines have higher compression ratios. If the octane number of a fuel isn't high enough it can lead to engine knocking this is where the fuel detonates before the fuel is at its maximum compressive state in the engine, this can cause damage and lower performance.
"Octane" is the measure of a gasoline's resistance to igniting before you want it to, and all gasolines have an octane rating. A Honda Accord runs on unleaded regular...so how you use "octane" fuel on an Accord is to go to your favorite gas station, push the button for the least expensive gasoline they have, and fill your car with it.
87 octane
87 octane
it is based on Octane levels, you have your standard 89,91,93 octane regular gas, and racing fuel is closer to 117 octane hope that helps
There is no cetane number for petrol. Cetane is a measurement of Diesel fuel and Octane is a measure of Petrol. Each is a measure of the combustion ability. Cetane is a measure of the amount of time from injection of the fuel into the combustion chamber and the actual ignition of the fuel. Diesel's ignite the fuel through compression and not spark as in a petrol engine.
87 octane
91 octane
