稀燃发动机 meaning in English
leb lean -burn engine
Examples
- Leb lean - burn engine
稀燃发动机 - Investigations on a lean burn engine show that nox can be removed by using hc and co in the exhaust gas as reducing agents . when the catalyst is used , the rate of nox conversion can reach a maximum of 74 . 4 % at 400
稀燃发动机台架实验结果表明，催化剂抗硫中毒、抗高温以及抗水蒸气能力较强；最大nox转化效率达74 . 4 % ；最大nox转化率排气温度点在400附近。 - First in an 150 - 550 temperature range , the influence of oxygen concentration , space velocity and propene concentration on the no conversion was investigated and then also the macro kinetics of propene oxidization and no reduction
本文研究了在pt al _ 2o _ 3催化剂上进行的hc - scr反应，用以稀燃发动机尾气的治理。首先在150 - 550温度范围内考察了氧气浓度、空速及还原剂浓度对no转化的影响。 - Investigations also show that the catalyst shows good heat resistance in the presence of water and demonstrates high capability for mitigating sox poisoning . in the end , a novel way controlling combustion is employed in a 1 . 342l s . i . engine , in which lean - burn , fast burn ( tumble ) and delay ignition make the engine provide much cleaner exhaust gas than that of a conventional premixed s . i . engine
最后综合采用机内净化和排气后处理并行策略，即稀燃、快燃（滚流） 、推迟点火的可控燃烧新方案，结合分子筛稀燃催化器，在稀燃发动机典型工况下，在保证燃油经济性较原机改善14 . 8 %时， nox的排放大幅降低。
