11. Fuel and Lambda The Stoichiometric AFR value is the AFR multiplier So for standard unblended gasoline its 14 7 If you set it to 14 7 the LM 2 display will show 14 7 AFR for Lambda 1 0 If you set it to 6 4 methanol the LM 2 will show 6 4 AFR for Lambda 1 0 You can look at Lambda as the percent of richness If running Lambda 0 85 12 5 AFR for gasoline you are running 15 rich For methanol 15 rich means 5 44 AFR That s where the value of Lambda comes in If you run blended fuels where you don t know the stoich value you look at Lambda and adjust to 10 20 rich depending where your max power is The value of richness required by an engine for max power does change relatively little fairly independent of fuel But if for example you adjust an engine running methanol to 12 5 AFR you would be running so lean that it would probably not even run The LM 2 can be used to read Air Fuel Ratio AFR or Lambda for an engine For gasoline driven engines the theoretically optimal air fuel ratio for efficiency is 14 7 pounds of air for every pound of fuel At this ratio theoretically all available oxygen in the air combines with all available fuel This ratio is called the stoichiometric ratio stoichiometric for different fuels are as follows Gasoline 14 7 LPG Propane 15 5 Methanol 6 4 Ethanol 9 0 CNG 17 2 Diesel 14 6 The measurement Lambda is the actual air fuel ratio over the stoichiometric ratio A Lambda measurement of 1
