Combustion Appropedia: The sustainability wiki
The Air/Fuel Ratio or AF is the ratio of mass of air to mass of fuel: AF= m air /m fuel. This is found by finding the product of the molar weight of components and their coefficient in the balanced chemical formula for combustion, and summing these components to find the molar mass of air. The components in air are usually O 2 and N 2.
