How to obtain gasoline octane rating
Thread Content
I would like to ask everyone: is the octane rating of gasoline currently calculated by manufacturers, or is it measured directly? If calculation is needed, could you provide the formula?
It was measured using an octane rating machine. . . . Of course, conversion is needed before harmonization. . . Generally, you can use the average of addition and multiplication to make a rough estimate. . . But in the end, it still has to be determined through actual testing. . . When gasoline leaves the factory, it is necessary not only for its research octane number to meet the specified standards, but also for another important parameter – the anti-knock index – to be within the required range. . . So it’s not just a matter of calculation; batch testing must be carried out. . . :lol
