摘要
本文将氢燃烧的化学反应机理与Chemkin多区火花点火燃烧模型耦合,分析压缩比、点火提前角等因素对氢燃料燃烧性能的影响,结果表明:当压缩比不同时,缸内温度随着压缩比的增大而略微下降,缸内压力随着压缩比的增大而增大;当点火提前角不同时,缸内温度变化不大,缸内压力随点火提前角的增大而增大。
In this paper, the chemical reaction mechanism of hydrogen combustion is coupled with the Chemkinmulti-zone spark ignition model to analyze the influence of compression ratio and ignition advance angle on the combustion performance of hydrogen fuel. The results showed that when the compression ratio is not at the same time, the temperature of the cylinder with the increase of the compression ratio and de- creases slightly, the cylinder pressure increases with the increase of the compression ratio; when the igni- tion advance angle is not at the same time, little change of temperature in the cylinder, the cylinder pres- sure increases with the increase of the ignition advance angle.
