基于离散小波变换的二甲醚HCCI爆震试验（Experimental Analysis of Knock in a DME HCCI Engine Using Discrete Wavelet Transform）
二甲醚 均质压燃 爆震
2009/5/22
在一台由柴油机改造为二甲醚进气道喷射的发动机上，用离散小波变换分析正常燃烧工况、爆震工况的缸内压力，计算其在各尺度细节部分的能量特征值，研究二甲醚HCCI燃烧的爆震特性。结果表明，正常燃烧工况、爆震工况缸内压力的能量特征值分布具有明显的规律。正常燃烧工况时，细节部分D3的能量特征值最大；爆震工况时，细节部分D1的能量特征值最大。转速升高或进气道喷射燃料添加LPG对正常燃烧工况、爆震工况缸内压力能量...
