WebThis means that if we switch to E85 and tune the engine to 0.85 lambda, the meter will still display 12.5:1 because the meter is still multiplying the measured lambda value of 0.85 by the programmed stoichiometric AFR of 14.7:1 In reality though the actual AFR is 0.85 multiplied by 9.8:1 which is the stoichiometric air fuel ratio of E85. 05:02. WebEmpirical studies have shown that oscillating the AFR around stoichiometry at an optimized AFR frequency, amplitude, and bias widens the catalyst window, thereby increasing catalyst conversion efficiency in the presence of unavoidable disturbances [1].
