采用LaVision公司特色的以高速图像增强器为核心部件构成的平面激光诱导荧光(PLIF)测试系统对透明单冲程压缩机用于均质混合进气压缩燃烧(HCCI)进行了实验研究。
In this study, experimental results of homogeneous
charge compression ignition HCCI of n-butane in a
single shot machine are presented. N-butane
measurements are compared with a multizone model.
Individual zones are calculated using a perfectly stirred
reactor and Chemkin chemistry. The influence of
temperature before combustion on heat release rate and
duration of combustion is shown in a sensitivity analysis.
As a perfect homogeneous temperature and fuel
distribution are difficult to establish under experimental
conditions, deviations from perfect homogeneity are
shown. The influence of a hot surface in the cylinder
head in terms of heat release rate and ignitability is
examined. Further, dual fuel injections of n-butane and
diesel are studied to trigger the n-butane ignition with a
defined start of combustion.
