| 摘 要： | 利用美国Lawrence L ivermore国家实验室公布的乙醇燃烧的复杂化学动力学机理和热力学数据,建立了乙醇HCC I燃烧模型。对模型中复杂化学反应动力学刚性问题采用了能够自动调节步长的Gear向后差分法。分析了进气温度、进气压力、压缩比、当量比等因素对燃烧特性的影响。计算结果对燃用乙醇的HCC I燃烧过程的模拟和分析提供了依据。

| Abstract: | A detailed HCCI combustion model for ethanol fuel is created using chemical kinetic mechanism and thermodynamics data published by the Lawrence Livermore National Lab in the US.The Gear's backward differentiation formulas(BDF) method,in which the step size can be automatically adjusted,is used to solve the complex problem of chemical reaction kinetics.The effects of intake temperature,intake pressure,compression ratio and air/fuel ratio on HCCI combustion characteristics are analyzed.The results provide a basis for simulating and analyzing HCCI combustion process of ethanol fuel. |
