How to Use the Air to Fuel Ratio Calculator

This calculator allows you to determine the air to fuel ratio based on various input parameters. Follow these guidelines to use the calculator accurately:

  • Enter the mass of air in grams.
  • Enter the mass of fuel in grams.
  • Enter the density of air in kg/m³.
  • Enter the density of fuel in kg/m³.
  • Enter the temperature of air in °C.
  • Enter the temperature of fuel in °C.
  • Enter the volume of air in liters.
  • Enter the volume of fuel in liters.
  • Click the “Calculate” button to see the results.

Explanation

The Air to Fuel ratio (AFR) is a critical parameter in the internal combustion engines. It is the mass or volume ratio of air to fuel present in the internal combustion engine.

This calculator computes AFR based on two different methods:

  1. Mass ratio: This is calculated by dividing the mass of air (in grams) by the mass of fuel (in grams).
  2. Volume ratio: This is derived by taking into account the densities and volumes of both air and fuel, using the formula: (Air Volume * Air Density) / (Fuel Volume * Fuel Density).

Limitations

While this calculator attempts to consider several parameters for an accurate AFR calculation, please be aware of the following limitations:

  1. The results are based on the entered values being accurate and valid. Any incorrect input will lead to incorrect results.
  2. Environmental factors such as altitude and humidity are not considered in this calculator.
  3. The temperature inputs are for reference and do not directly affect the AFR calculation in this tool.
