摘　　要：为应对国六排放法规,提高脱附流量是降低蒸发排放和加油排放物的重要手段。基于流体力学相关流动理论和发动机结构参数,建立高压脱附系统工作控制模型并进行模型标定。试验表明,开环控制高压脱附系统同时兼顾鲁棒性和准确性,是当前条件下大规模产业化增压脱附系统的理想控制算法。In response to the China VI emission regulations,the application of turbo engine high-pressure purge system is an important mean of reducing evaporative emission and ORVR emission.A control model of high-pressure purge system was established and calibrated based on the flow theory and structural parameters of a mature engine.Test results show that the open-loop control system has good robustness and accuracy,which is an ideal control algorithm for industrial purge system under current conditions.
