What Is Air-Fuel Ratio & It’s Importance in the Engine?

WebApr 15, 2024 · The air-to-fuel ratio was calculated based on the flow rates of air and fuel supplied into the combustion chamber. The A/F ratio is a crucial parameter for engine performance. The higher A/F ratio favors better fuel combustion inside the cylinder and results in higher energy release with lower exhaust gas emissions of CO and CO 2 . WebThe ideal (theoretical) air fuel ratio, for a complete combustion, is called stoichiometric air fuel ratio. For a gasoline (petrol) engine, the stoichiometric air fuel ratio is around 14.7:1. This means that, in order to burn completely 1 kg of fuel, we need 14.7 kg of air. data type object python
