本文介绍了一种描述双燃料柴油机燃烧过程的热力学—化学反应动力学数学模型,它用含有14种化学成分的32个化学反应方程来模拟甲烷空气混合气的燃烧过程,同时还能揭示各种控制参数对双燃料柴油机性能及燃烧过程的影响程度.试验表明在较为宽广的运行范围内计算值与实测值相当一致.说明该燃烧模型能较为满意地预测双燃料柴油机的性能和排放.
This paper presents a thermodynamic-chemical kinetic mathematical model describing the combustion process of a dual-fuel diesel engine, which simulates the combustion of methane-air mixture with 32 chemical reaction equations containing 14 chemical components and also reveals various The influence of the control parameters on the performance and combustion process of the dual-fuel diesel engine is shown.The results show that the calculated values are in good agreement with the measured values over a wide range of operating conditions, indicating that the combustion model can predict the performance and emissions of the dual-fuel diesel engine more satisfactorily.
