摘要

根据严格的巴拉特第六阶段排放标准,目前通过各种设计的柴油颗粒过滤器、催化转化器、挡板过滤器来控制柴油机排气中的颗粒物。本研究设计了一种横截面积随长度增加的螺旋风管装置。该管道沿内壁固定有一层耐热多孔材料衬里。该装置通过发动机排气进气管安装在压缩点火发动机驱动车辆的尾管上,其出口与排气系统的尾管相连。该装置将在沿螺旋壁的耐热多孔内衬中收集颗粒物质,从而减少颗粒物质。对螺旋流设计进行了仿真,结果表明螺旋流设计符合流动参数的可接受性。开发的时尚设计可以很容易地在现有车队中进行改装,使其符合严格的法定排放标准。

Particulate Matter Separator Analysis for Compression Ignition Engines Adhering Bharat Stage VI Norms
In compliance of the stringent Bharat Stage VI emission norms control of particulate matter in diesel engine exhaust emission is currently achieved through diesel particulate filter, catalytic convertors, baffle filters of various designs. In the present research a device comprising of a spiral duct with increasing cross sectional area over the length is designed. The duct has a lining of heat resistant and porous material fixed along the inside walls. The device is fitted at the tail pipe of compression ignition engine driven vehicle through an inlet pipe of engine exhaust with outlet connected to the tail pipe of the exhaust system. This device will collect the particulate matter in the heat resistant porous lining along the walls of the spiral thus reducing the particulate matter. The spiral flow design was simulated and was found to be in line of acceptance of flow parameters. The developed sleek design can be easily retrofitted in the existing fleet of vehicles making them compliant for stringent statuary emission norms.
