本文对汽油机最高爆发压力的循环变动进行了研究。
This paper studied the cycle-to-cycle variation of in-cylinder peak pressure in gasoline engines.
二甲醚喷油延迟角比柴油大,最高爆发压力、最大压力升高率、燃烧噪声比柴油低;
Since the ignition delay of DME is shorter than that of diesel, thus makes the lower value of maximum cylinder pressure, maximum rate of pressure rise and combustion noise.
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.
