摘　　要：利用专用软件建立了PA6型柴油机燃油系统数值模型,分析了相关参数对该燃油系统的影响并指出存在的问题,在此基础上提出了改进方案,重点对高压油腔压力、喷油量和雾化性能等进行了改进前后的对比分析。分析显示,改进后燃油系统最高喷射压力达到175MPa,喷油量基本保持不变,燃油雾化质量得到提高。The numerical model of PA6 fuel injection system was set up by a special software.The influence of relative parameters on the fuel injection system are studied and the problems are pointed out,based on which the improvement programme are proposed.High injection pressure,fuel injection volume and atomization performance are especially analyzed,and the parameters before and after the improvement are compared.It shows that after the improvement,the highest injection pressure can reach 175 MPa,fuel injection volume remains about the same and the quality of atomization is enhanced.
