【摘要】 本文建立了一个直喷式柴油机的多区准维油滴蒸发燃烧模型,在此基础上采用Arrhenius型公式对实际过程中极为复杂的碳烟生成历程进行了模拟。在一台四冲程直喷式柴油机上对该模型进行了标定和试验验证,试验结果表明该模型对发动机变工况、变参数运行时的碳烟生成量有较好的预测能力。更多还原

【Abstract】 In this paper, a multi-zone drop evaporation combustion quasi-dimension model for direct injection diesel engine is established. Based on this model, the complex soot formation process is simulated via a group of Arrhenius formulas. This soot prediction model has been calibrated and tested on a 4-stroke DI diesel engine, the results indicate that the model is capable of predicting soot formation of engine running under variable condition and parameters.更多还原
