Air-Fuel Ratio (AFR)
Air-fuel ratio is the mass ratio of air to fuel present during combustion. When all the fuel is combined with all the free oxygen in the combustion chamber the mixture is chemically balanced and this air to fuel ratio (AFR) is called the stoichiometric mixture (often abbreviated to stoich). AFR is an important measure for anti-pollution and performance tuning considerations.
