Methanol lambda chart
4 Jun 2019 Methanol as motor fuel has gained interest in recent years due to its low price, easy criteria, as seen in the chart below(2). As shown in this figure, the Flex Fuel Kit receives feedback from the ECU taken from the lambda. Methanol is an unusual fuel in that if we looked at power vs lambda, we find that there is very little drop off in power as we move rich. In fact the rich limit of methanol fuel is often enforced by the ignition system failing to ignite the fuel/air charge. Lambda was computed for the previous example of a blown methanol racing engine running mechanical fuel injection (MFI) as follows: Actual AFR = 3.4 to 1 (weight of air & fuel computed with MFI jetting calculator for the ‘best-run’ setup of the blower / fuel system combo). For a great software program try Larry Meaux's Pipe Max. His program is excellent and will provide a lot of info. Pipe Max. Back to Calculators Index These equations are for recreation only. Im not fully understanding this yet, but a chart might be what i need to finally get it. I need a chart for methanol to gasoline lambda. I still dont know how to figure what lambda or AFR to shoot for when spraying methanol injection. That's a lambda value of .796-.905, which is equivalent to a methanol (based on 6.5 AFR stoich) AFR value of 5.17-5.88. So it depends on what AFR scale you're talking about. If you want to tune to a methanol stoich value of 4:1 it would be equivalent to tuning on a gas scale with a target of ~9.0 AFR. How stoichiometric air-fuel ratio is calculated. In order to understand how the stoichiometric air-fuel ratio is calculated, we need to look at the combustion process of the fuel. Combustion is basically a chemical reaction (called oxidation) in which a fuel is mixed with oxigen and produces carbon dioxide (CO 2), water (H 2 O) and energy (heat). Take into account that, in order for the
Methanol: 6.4:1 Given the known stoich value of a specific fuel, we can go back to our 3 states (rich, stoichiometric, lean) The lambda value at the stoichiometric air fuel ratio for ANY fuel is always equal to a value of 1.00. The easiest way to understand this is to remember what the stoichiometric AFR actually is. Again, stoichiometric
2 Oct 2018 Air/Fuel Ratio or Lambda is a precise way of doing this. Using methanol as an example, the stoichiometric AFR is approximately 6.5 to 1. 5 Feb 2015 In the case of methanol, an air-to-fuel ratio of 4:1(4 parts air to 1 part fuel) is considered slightly on the rich side, but will allow the engine to make Methanol, CH3OH, 6.47:1. Ethanol Image: Engine power and fuel consumption function of air-fuel ratio (lambda). In the figure Much closer to the chart. This chart shows how different Air/Fuel ratios affect emissions, fuel economy For a racing fuel like METHANOL alcohol, the stoichiometric A/F ratio is 6.5:1. If the Air/Fuel mixture is RICH (less than the stoichiometric ratio), Lambda will be 21 Feb 2020 The solute-free mass fractions of methanol extended from 0.3 to 1.0.

Nitromethane is very expensive and dangerous to handle. The interesting alternative to gasoline is Methanol. Methanol will make more power, typically around 10% more power than a similar engine running gasoline. Some things to consider in running methanol is your fuel system will have to be completely changed / upgraded.
