Abstract

In compliance with the stringent BS-VI emission norms, control of particulate matter in diesel engine exhaust emission is currently achieved through diesel particulate filters, catalytic convertors, and baffle filters of various designs. In the present study a device comprised of a spiral duct with an increasing cross-sectional area over the length is designed and developed. The duct has a lining of heat-resistant and porous material fixed along the inside walls. The inlet of the devices is connected to the outlet of the tailpipe of the exhaust system. The device will collect the particulate matter in the heat-resistant porous lining along the walls of the spiral. The developed device is simple, economical and easily serviceable. The developed spiral duct particulate matter separator was tested on diesel vehicles, and the smoke density of tailpipe emission was measured in terms of the light absorption coefficient. During the analysis it was found that there is a reduction in light absorption coefficient by 25.37%. The developed design also overcomes the clogging problem of the exhaust system, which is a cause of backpressure in the case of conventional particulate filters. The design of the device is such that it can be easily retrofitted in the existing fleet of vehicles, making them compliant with stringent statuary emission norms.
新型内燃机用螺旋导管颗粒物分离器的研制
根据严格的BS-VI排放标准,目前柴油发动机尾气排放中的颗粒物控制主要通过各种设计的柴油微粒过滤器、催化转化器和挡板过滤器来实现。在本研究中,设计和开发了一种由螺旋导管组成的装置,该装置的横截面积随长度的增加而增加。该管道有一层耐热多孔材料衬里,沿着内壁固定。所述装置的入口与排气系统的排气管出口相连。该装置将在沿螺旋壁的耐热多孔衬里收集颗粒物质。所研制的装置简单、经济、维修方便。研制的螺旋风道颗粒物分离器在柴油车上进行了试验,并通过光吸收系数测量了尾气排放的烟密度。在分析过程中,发现光吸收系数降低了25.37%。开发的设计还克服了排气系统的堵塞问题,这是传统颗粒过滤器情况下背压的原因。这种装置的设计可以很容易地在现有的车队中进行改装,使它们符合严格的法定排放标准。
