稀燃 meaning in Chinese
lean-burn
Examples
- Modern engine thin - petrol technique
现代发动机稀燃技术 - Leb lean - burn engine
稀燃发动机 - Lean - burn engine is operated at air - fuel ( a / f ) ratios of 21 : 1 and above , in addition , ignition is delayed , as a result of these technique , the nox emissions are very low
同时，本研究也成功地运用了由原位合成技术制作的分子筛堇青石整体式分子筛催化器，去除稀燃nox排放。 - 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。
