本文构建了一个适用于HCCI燃烧的PRF化学反应动力学骨架机理。该机理包含40种组分和65个反应。通过与激波管、喷射搅拌反应器、流动反应器和HCCI发动机的实验数据对比表明,新机理适用于多种反应器,可以较准确地计算着火点及关键组分的演变规律,并且在不同的温度、压力和当量比下具有较好的性能。在HCCI发动机的单区模型计算中,对于燃料PRF 91.8和PRF 70,骨架机理计算结果与Curran等人的详细机理计算结果基本相同。 In this paper, we have constructed a kinetic framework for PRF chemistry that is suitable for HCCI combustion. This mechanism contains 40 components and 65 reactions. The comparison of experimental data with shock tube, jet-stirred reactor, flow reactor and HCCI engine shows that the new mechanism is suitable for many kinds of reactors, and the evolution law of ignition point and key components can be calculated more accurately. Temperature, pressure and equivalent ratio has better performance. In the single-area model calculation of HCCI engine, the calculation results of the skeleton mechanism are basically the same as those of Curran et al. For the PRF 91.8 and PRF 70 fuels.
