Calculate Octane Ratio



Formula

To calculate the Octane Ratio (R):

\[ R = \left( \frac{V_o}{V_t} \right) \times 100 \]

What is an Octane Ratio?

The octane ratio is a measure of the proportion of octane in a fuel mixture. It is typically expressed as a percentage and is used to indicate the quality and performance characteristics of the fuel. Higher octane ratios generally mean better resistance to knocking and more efficient combustion, which is particularly important in high-performance engines. The octane ratio is a crucial factor in determining the fuel’s ability to withstand compression without detonating.

Example Calculation

Let's assume the following values:

Using the formula:

\[ R = \left( \frac{20}{50} \right) \times 100 = 40\% \]

The Octane Ratio is 40%.
