摘要: 为了改善井下工人工作环境，减少井下柴油机NOx, CO, HC等污染物的排放，根据防爆柴油机的工作环境及排放法规要求，针对某型防爆柴油机不同进气流量下的动力性和排放性进行了试验研究，确定了适当的防爆柴油机进气流量。试验结果表明，减小进气流量使防爆柴油机动力性有一定降低，也使得排放中的烟度略有增加，但却一定程度上降低了NOx的排放。

Abstract: In order to improve working environment of underground coal miners and reduce emissions of pollutants such as NOx, CO, HC, etc., power and emission performances of a certain type of explosion-proof diesel under different air intake flow were studied according to working environment of explosion-proof diesel and emission regulations, and the appropriate air intake flow of explosion-proof diesel was determined. The test results show that reducing air intake flow will reduce power performance of explosion-proof diesel, and increase smoke slightly, but it will also reduce the emissions of NOx.
