The formula to calculate the Air Fuel Ratio (AFR) is:
\[ AFR = \frac{m_{air}}{m_{fuel}} \]
Air to Fuel ratio is the ratio of the mass of air to the mass of fuel during combustion. It dictates the efficiency of the combustion and the performance of the engine. Mass of Air is both a property of air and a measure of its resistance to acceleration when a net force is applied. Mass of Fuel is both a property of fuel and a measure of its resistance to acceleration when a net force is applied to it.
Let's assume the following values:
Using the formula:
\[ AFR = \frac{6}{2.8} \approx 2.14285714285714 \]
The Air Fuel Ratio is approximately 2.14285714285714.
