滞燃期 [动力] ignition delay period
- 给出了十六烷值对滞燃期、最大压力升高率、最高燃烧压力以及几种燃烧压力升高比影响的试验结果;
Experimental results showing the effects of cetane number of diesel fuel on the ignition delay, peak cylinder pressure, maximum rate of pressure rise, etc. are given. - 柴油中添加二甲氧基甲烷对滞燃期和急燃期影响不大,但总燃烧持续期随混合燃料中二甲氧基甲烷的增加而缩短。
Adding DMM in diesel fuel did less influence on the ignition delay and rapid burning duration while the total combustion duration would decrease with the increase of DMM in diesel fuel. - 结果表明:与柴油相比,发动机燃用二甲醚时的喷油延迟期延长,滞燃期缩短,最高爆发压力和最大压力升高率均低于柴油机。
The results show that DME operation has longer injection delay, lower maximum cylinder pressure, lower ratio of pressure rise, shorter ignition delay in comparison with diesel operation.
