您要查找的是不是：
- The results reveal that the increase of compression ratio advances the ignition timing of two stages, shortens the interval of the two stages and combustion duration. 結果表明：隨著壓縮比的升高，二甲醚的兩階段著火均有提前，且間隔減小，燃燒持續期縮短；
- While, the main parameters which show important influence on CO emissions are the maximum combustion temperature, pressure rising rate, IMEP, and combustion duration. 而影響CO的參數主要有最高燃燒溫度、最大壓力升高率和平均指示壓力。
- Early exhaust valve closing ( EVC ) timings result in high residual fractions in the cylinder, decreasing air mass in cylinder per cycle, increasing combustion duration, and decreasing IMEP while the pumping loss is decreased. 排氣門關閉越早,缸內的殘餘廢氣量增加,每循環進氣量減少,燃燒持續期變長,PIMEP減小,然而泵氣損失減小;
- 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. 柴油中添加二甲氧基甲烷對滯燃期和急燃期影響不大，但總燃燒持續期隨混合燃料中二甲氧基甲烷的增加而縮短。
