摘要
本文建立了火花点火发动机顶岸间隙、缸套壁面润滑油膜和缸内壁面积碳层处未燃碳氢生成和释放过程的预测模型以及缸内、排气管中未燃碳氢氧化模型,并利用模型预测了发动机排气未燃碳氢量。计算结果表明,本模型的预测结果能较好地与实验结果吻合。
In this paper,a prediction model of unburned hydrocarbon formation and desorption in topland crevice,cylinder wall lubricanting oil layers and combustion chamber deposit layers in spark ignition engine are established,the oxidation models of hydrocarbons in cylinder and exhaust pipe are also given and the engine exhaust unburned hydrocarbons is calculated by using this model.The calculation results show that the prediction results have good agreement with the experimental data.
