Luft-brændstofforholdsberegner

Beregn luft-brændstofforholdet og lambdaværdien ud fra luft- og brændstofmasse.

Introduktion

Air-Fuel Ratio Calculator — Calculate air-fuel ratio and lambda from air and fuel mass. Enter Mass of air, Mass of fuel to get an instant, accurate result.

Formel

AFR = mass of air / mass of fuel. Lambda (λ) = actual AFR / stoichiometric AFR (14.7:1 for gasoline) — lambda of 1.0 is a perfectly balanced (stoichiometric) mixture.

Trin for trin

  1. Enter the Mass of air.
  2. Enter the Mass of fuel.
  3. Click Calculate to see your result instantly.

Eksempel fra virkeligheden

Example: With Mass of air = 14, Mass of fuel = 1, the Air-Fuel Ratio Calculator gives Afr: 14, Lambda: 0.9524.

Ofte Stillede Spørgsmål

What does lambda greater or less than 1 mean?
Lambda above 1.0 is a lean mixture (more air relative to fuel); below 1.0 is rich (more fuel relative to air).
Why is 14.7:1 used as the stoichiometric baseline?
That's the theoretically ideal air-to-fuel ratio for complete combustion of gasoline; other fuels (like E85 or diesel) have different stoichiometric ratios.
What inputs does the Air-Fuel Ratio Calculator need?
You'll need to provide: Mass of air, Mass of fuel. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Air-Fuel Ratio Calculator?
The Air-Fuel Ratio Calculator applies the formula exactly as calculated — AFR = mass of air / mass of fuel. Lambda (λ) = actual AFR / stoichiometric AFR (14.7:1 for gasoline) — lambda of 1.0 is a perfectly balanced (stoichiometric) mixture. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Air-Fuel Ratio Calculator free to use?
Yes, the Air-Fuel Ratio Calculator is completely free, requires no signup, and runs instantly in your browser.

Om Luft-brændstofforholdsberegner

The Air-Fuel Ratio Calculator uses a real, verifiable formula — AFR = mass of air / mass of fuel. Lambda (λ) = actual AFR / stoichiometric AFR (14.7:1 for gasoline) — lambda of 1.0 is a perfectly balanced (stoichiometric) mixture. — so results are accurate every time, not an approximation.
