摘要
开发了采用壁流式蜂窝陶瓷作为过滤材料,利用红外辐射及柴油机废气进行再生的新的柴油机排放微粒后处理系统.该系统具有结构简单、可靠性高、实用性好的特点.在6110A柴油机台架上对系统的样机进行了碳烟过滤特性及再生特性的试验研究.试验结果表明:系统的碳烟过滤效率高达95%,排气背压低,再生效率超过89%,工况适应性好.后处理系统通过废气流量及再生点背压对红外再生过程进行控制的方法是有效的.
A new type of diesel particulate filter （DPF） system using honeycomb ceramic filter was developed successfully by utilizing the infrared regeneration technique. The DPF system has features of simple structure, high reliability and good applicability. The characteristics of filtration and regeneration of the DPF system were investigated in a 6110 D.I. diesel engine. The experimental results show that the DPF system has 95% high trapping efficiency, and over 89% high regeneration efficiency, low back pressure, good adaptability to engine operating conditions. The regenerating process of the DPF system was proven effective through controlling the exhaust flow rate and the back pressure of regeneration point.
