Optimum air/fuel ratio for a gasoline engine
WebMar 26, 2024 · For their part, Sarthak et al. 6 have shown that an optimum between a hydrogen/diesel ratio of 20% in an engine with exhaust gas recirculation (EGR rate of 10%) is an optimum between the emission of pollutants and the achievement of good performance. Another alternative heavily explored by researchers is dual-fuel gas/diesel operation. WebThis term defines the ratio of air and fuel that will result in theoretically perfect combustion, ie all of the available oxygen and fuel is combusted. For normal pump fuel, this stoichiometric air fuel ratio is 14.7:1 which means that for every kilogram of fuel the engine burns, it consumes 14.7 kilograms of air.
