Particulate Matter Separator Analysis for Compression Ignition Engines Adhering Bharat Stage VI Norms

Abstract

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.
