Carburetor Basic Principles

It is defined as: A/F = Mair/Mfuel If we consider this ratio from a chemical point of view, the value of the stoichiometric A/F ratio is the one that allows complete combustion, without leaving either excess air (lean mixtu- res) or unburned fuel (rich mixtures) Stoichiometric A/F The stoichiometric A/F ratio de- pends on the fuel type.
