Using a combustion model some problems such as: the relationship between ignition delay and fuel concentration, the relationship between soot concentration and the equivalent ratio of mixture have been helped forward on further investigation in combustion and soot formation in diesel engine. 利用该燃烧模型进一步研究柴油机的燃烧和碳烟生成中的一些问题:如点火延迟时间与混合气浓度的关系,排气中的碳烟浓度与混合气油气当量比的关系。
Each of three control methods can achieve the level of emissions in lean combustion gasoline engines equivalent to Europe ⅲ standard and it can save fuel for 8 to 10 percent. 三种综合控制策略均可使稀燃汽油机稳态排放达到欧Ⅲ标准的相当水平,节油率为8%-10%。
The result shows that after applying the design of such combustion system and adopting suitable spray timing and gas motion, in the case of combustion with mixture equivalent air/ fuel ratio, the result is similar with that of homogeneous premixed combustion. 结果表明,采用该燃烧室设计方案并与适当的喷雾、气流运动相配合,在当量燃空比时,使用汽油缸内直喷能获得与均质预混燃烧相近的效果。
As to the energy generation system, taking coal combustion as an example, after combustion the main pollutants are analyzed in details, and then the environment impact is evaluated with the equivalent evaluation in the chemical process system. 对于能量产生系统,以煤燃烧为例,对燃烧后的主要污染物进行了详细地分析和计算,并利用工艺流程系统中的当量评分来计算环境的影响。
We take coal combustion heat value for 29306kJ/ kg, so the recovery heat is equivalent to 17000 tons coal. 取标煤的燃烧热值为29306kJ/kg,则所回收余热量相当于年节约标煤1.7万吨。
