How to Calculate the Stoichiometric Air-fuel Ratio

The stoichiometric air-fuel ratio is an important parameter of fuels. When designing an engine for a particular fuel, it's important to know how much air is needed to completely burn a certain amount of fuel. This article describes this ratio and presents an easy way to
