Experiments were carried out on a HCCI platform to evaluate the effects of cetane number and octane number on the HCCI combustion characteristics and emissions using n-heptane, RON25, RON50, RON75, RON90, and iso-octane.

进一步在发动机上对正庚烷、RON25、RON50、RON75、RON90和异辛烷在不同负荷下的HCCI燃烧特性和排放特性进行了试验研究。

The interfacial polarization resistances were unvaried during this period,suggested that the SDC modified anode was stable for the direct utilization of octane,and slight degeneration in the performance was associated mainly with the loss of OCV,which was possibly derived from a little carbon deposition within the SDC-coated anode where the level is so low that it almost has no effect to cause severe damage to the anode. The fuel composition and operation conditions had remarkably influence on the cell durability,implied that the stability of the fuel cells could be further improved by varying the iso-octane/O2 ratio and conducting a continuous operation.

燃料组分和测试条件对电池稳定性有着较大影响，说明通过改善O2/iso-octane比例以及维持电池在更长时间内放电能够获得更好的长期输出性能。

The octane number of 5 substances were predicted using the new methods.The results show that the second level group contribution method exhibits significant improvements in accuracy and should be used for estimating the octane number of branched and ring hydrocarbons.In cases of simple straight chain bydrocarbons, however,the first level group contribution method should be used.

用新方法对未参加回归的五种物质的辛烷值进行了预测，结果表明对于含有支链和环的烃应采用第二水平基团法估算其辛烷值，对简单的直链烃采用第一水平基团法估算其辛烷值。
