本研究的目的是评估燃料如何通过其特性来增加 HCCI 条件下可实现的最大负载。首先制定了具体程序。其次，使用该程序，测试了一组使用 Jet B 作为基础燃料并具有不同十六烷值（33 至 40）和不同化学成分（通过添加烯烃和环烷化合物反应产物）的燃料。我们得出的结论是，具有低十六烷值、高挥发性和适当化学成分的燃料可以将 HCCI 运行范围提高 30% 以上，而在传统柴油燃烧模式下性能不会有太大下降。
The aim of this study is to assess how the fuel, through its characteristics, could increase the maximum load achievable in HCCI condition. First a specific procedure has been developed. Second using this procedure, a set of fuels using a Jet B as base fuel and having different cetane numbers (from 33 to 40) and different chemical compositions (via the addition of reactive products which are olefinic and naphtenic compounds) have been tested. We conclude that a fuel having a low cetane number, a high volatility and an appropriate chemical composition could improve the HCCI operating range of more than 30% without a too large decrease of the performance under conventional Diesel combustion mode.
