The intensity of the gas backflow and axial swirl ond the dilution in the afterburner are enhanced by increasing the air-to-fuel ratio, and then the combustion efficiency is improved. 提高空燃比,可增强补燃室中燃气的回流和轴向涡流强度,加大掺混力度,从而提高燃烧效率。
Due to the model with fuel supply, the gaseous hydrogen was injected into the combustion chamber at air-to-fuel factors exceeding the stoichiometric ratio. 在实验中,模型中有燃料供给:把气态氢以超过化学量比率的空气燃料因子注入到燃烧室。
And air-to-fuel ratio, blending ratio, etc, are adjusted on-line by varying the injection durations of the two fuels. 通过调整两种燃料的喷射脉宽,可以实现对混合燃料的空燃比、混合比例等参数的调整。
The conversion results of the pumping cell current can provide the information about the oxygen content or air-to-fuel ratio of the engine exhaust gases. 泵电流的转换结果可反映废气的氧含量值或空燃比值。
