Relative Air-Fuel Ratio evaluator uses Relative Air Fuel Ratio = Actual Air Fuel Ratio/Stoichiometric Air Fuel Ratio to evaluate the Relative Air Fuel Ratio, Relative Air-Fuel Ratio is a concept used to describe the actual air-fuel mixture present in an engine compared to the ideal or chemically correct mixture(Stoichiometric A/F ratio). It compares the actual air-fuel mixture in the engine to the stoichiometric ratio. A Relative AFR of 1 indicates a stoichiometric mixture. Values less than 1 represent rich mixtures, and values greater than 1 indicate lean mixtures. Understanding Relative A/F ratio is crucial for engine performance and emissions. Relative Air Fuel Ratio is denoted by Φ symbol.
