摘要
利用燃烧理论、波动理论、有限元理论，研究直喷式柴油机燃烧压力振荡特性．研究表明，直喷式柴油机燃烧压力振荡具有多阶共振频率，实机缸内燃烧压力振荡是多个共振模态的叠加．经试验验证，本文计算结果与试验吻合较好．
Based on the wave theory, finite element theory and combustion theory, properties of combustion pressure oscillation in D. I. diesel engines are studied. The results show that the combustion pressure oscillation possesses multiple resonance frequencies, and the oscillation is the superposition of many modes in the real combustion chamber. The calculation results are in good agreement with the measurements.
