摘　　要：采用自燃点法对硝酸戊酯和硝酸异辛酯的性能进行了试验研究。试验结果表明:两种添加剂添加量为0. 6%时能降低柴油的自燃点32°C^54°C,提高柴油十六烷值10~16个单位,硝酸戊酯的性能优于硝酸异辛酯,两者复合使用时,硝酸戊酯和硝酸异辛酯之间存在对抗效应。将硝酸戊酯和硝酸异辛酯以1∶2质量比配成复合添加剂,能明显降低柴油机碳烟排放。The autoignition temperature method was adopted in this paper to investigate the performance of amyl nitrate and isooctyl nitrate. The results showed that the autoignition temperature progressively decreases by 32°C to 54°C and the cetane number of diesel fuel increases by 10-16 when the fuel blended with 0.6% of amyl nitrate or isooctyl nitrate. Amyl nitrate is more effective than isooctyl nitrate when they are used independently; there exists antagonism between these two additives when they are used together. The smoke emission progressively decreases when amyl nitrate and isooctyl nitrate are blended as the diesel fuel additive with the ratio of 1:2.
