Air Fuel Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Air to Fuel Ratio = Mass of Air/Mass of Fuel
AFR = m_air/m_fuel
This formula uses 3 Variables

Variables Used

Air to Fuel Ratio - Air to Fuel ratio is the ratio of the mass of air to the mass of fuel during combustion. It dictates the efficiency of the combustion and the performance of the engine.
Mass of Air - (Measured in Kilogram) - Mass of Air is both a property of air and a measure of its resistance to acceleration when a net force is applied.
Mass of Fuel - (Measured in Kilogram) - Mass of Fuel is both a property of fuel and a measure of its resistance to acceleration when a net force is applied to it.

STEP 1: Convert Input(s) to Base Unit

Mass of Air: 6 Kilogram --> 6 Kilogram No Conversion Required
Mass of Fuel: 2.8 Kilogram --> 2.8 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

AFR = m_air/m_fuel --> 6/2.8

Evaluating ... ...

AFR = 2.14285714285714

STEP 3: Convert Result to Output's Unit

2.14285714285714 --> No Conversion Required

FINAL ANSWER

2.14285714285714 ≈ 2.142857 <-- Air to Fuel Ratio
