The air-fuel ratio (AFR) denotes the proportion of air to fuel in a combustion process, pivotal for efficient energy production. Represented as a ratio, it measures the volume or mass of air relative to that of fuel present in an engine's intake system. Achieving the optimal AFR is crucial for engine performance, emission control, and fuel economy. A stoichiometric ratio of 14.7:1 (for gasoline) ensures complete combustion, minimizing emissions. Different applications demand varying ratios; lean mixtures (excess air) enhance fuel economy but may compromise power, while rich mixtures (excess fuel) boost power output but increase emissions. AFR serves as a cornerstone in automotive engineering, balancing performance and environmental concerns.
