| 摘 要： | 本文应用微机检测发动机稳定性指标,在一台采用涡流室火花塞组成快速燃烧系统的汽油机中,对影响燃油消耗率、NO_x排放和稳定性指标的主要参数如空燃比、点火提前角和废气再循环率进行了试验研究。结果进一步表明:在稳定性指标制约条件下,稀燃能节油,但不能降低NO_x排放;EGR能降低NO_x排放,但不能节油。

| Abstract: | In this paper, the effects of air-fuel ratio, ignition timing and exhaust gas recirculation ratio on fuel consumption, NOx emission and engine roughness index are experimentally studied. Test results indicate that under the restriction of engine roughness index, only the fuel economy may be improved by lean combustion, but not NOx emission, and EGR can lower down NOx emission, but not fuel consumption. |
