摘　　要：利用先进的内燃机燃烧学和热力学模型,建立了基于模糊诊断技术的柴油机故障诊断方法,应用数理统计方法确定了柴油机工作过程参数隶属度函数,构造了模糊故障诊断矩阵,并应用计算机技术实现了对柴油机常见故障的模糊诊断,在柴油机故障诊断应用中取得了良好的效果。A new diesel engine fault diagnosis system based on fuzzy diagnosis technology has been performed with the advanced combustion model and thermodynamic method. By statistical analysis of the engine working parameters, a fuzzy fault diagnosis matrix for diesel engine is built. The system shows the good effect in practical activities.
