烟尘排放
Examples
- Numerical analysis of reduction in mixture concentration and soot emissions in a diesel engine by swirl
涡流运动降低柴油机混合气浓度及碳烟排放的数值分析 - Under different rev and loads , the optimal diesel / alcohol proportion would be different . in order to find out the change rule of optimal diesel / alcohol proportion , an orthogonal regression rotating experiment of three factors ( rev , diesel / alcohol proportion and load ) at five levels has been carried out . based on the experiment , four regression equations including energy consumption , soot emission , noise level , and power equations concerning the three factors have been established
在性能试验的基础上，还进行了三因素五水平的二次正交回归旋转组合试验，建立了能耗率、烟度、噪声、功率与转速、酒精掺烧率及负荷率之间的回归模型，通过分析可知，这些模型具有较高的可信度；利用这些模型，本文最后对不同工况下的最佳酒精掺烧率进行优化分析，并利用正交多项式回归，求出了最佳掺烧率与转速、负荷之间的回归模型，该模型在今后的深入研究中将起到一定的指导作用。 - The results of the experiments show that the soot emission decreased greatly and the nox emission was improved , while co and hc emission increased but still lowered than gasoline engine , the power output and torque of the engine have not been influenced and the specific energy consumption was improved
试验结果显示，这种新型的燃烧模式不仅改善了发动机的碳烟排放，而且no排放也得到了改善，而hc 、 co排放则较原机严重，但还是低于汽油机的排放水平；发动机的动力性能未受影响，能耗率有所改善。 - This paper introduced a new partial premixed compound combustion mode engine in which some methanol was premixed in the introduction charge of the diesel . in such combustion mode ^ the premixed combustion part was increased , the diffusion , ambient was changed from air to methanol / air mixture for decreasing soot emission of the engine
本文介绍了一种新型燃烧模式，该燃烧模式是在柴油机的进气中预混一定浓度的甲醇，从而大大增加了柴油机中预混合燃烧比例，原有的扩散燃烧的环境也因是在甲醇蒸汽和空气的预混合气中而有了显著的改变。
