lean combustion meaning in English
稀薄燃烧
Examples
- Mean while , the iouver concentrator structure principle is analyzed , the iouver puiverized coal concentrator is studied on the bases of both laboratory and production . lt is discovered from the experiments that the louver horizontai rich / lean combustion pulverized coal burner has advantages of simple in structure , low resistance and adjustment of pc concentration
同时，重点分析了百叶窗浓缩器的结构原理，并在试验台上和现场对百叶窗煤粉浓缩器进行了大量的试验研究，结果表明：百叶窗式水平浓淡煤粉燃烧器具有结构简单、阻力损失小、分离调节方便等一系列优点。 - Engine , the fuel consumption decreases by about 19 . 1 % . on the other hand , the fuel consumption of quasi - homogenous mixture lean combustion decreases by about 6 . 5 % compared with homogenous lean mixture combustion . three - ways catalyst ( twc ) + optimizing afr technology is used to remove nox emissions in oxygen containing exhaust gas
本研究运用三效催化器+空燃比优化控制技术，利用三效催化器能一定程度降低nox排放的特点，控制发动机在优化空燃比下工作，将稀燃后排气中剩余不多的nox进一步催化。 - It is firstly found that the nox concentration increases rapidly when is less than 0 . 75 , which complements the staged combustion and the rich - lean combustion that are well considered currently as low nox combustion . it does not mean that the combustion must be the low nox combustion when < 1 . there is a limited least value of air excess coefficient
对目前普遍认为的分级燃烧和浓淡燃烧可以降低no _ x排放的提法给予补充，即对一次过量空气系数有一个最小值限定，不是小于1的任何值都可以，低于最小限定值将是不利的，而且一次过量空气系数有一个最佳值。
