It is very significant to define the ignition delay in the cylinder of Diesel Engines.
柴油机气缸内滞燃期的确定具有很大的意义。
With the decrease of compress ratio, HC emissions were increased and the ignition delay was prolonged.
随压缩比的降低，滞燃期延长，HC排放明显增加。
The results are better, which show that all portions of propellant are ignited, and the ignition delay is shortened.
计算结果比较理想，全部推进剂都被点燃，并且点火延迟时间减小了。
