Design analysis of spiral duct particulate matter separator for IC Engines for compliance of BS VI norms 2020-28-0331

In compliance of the stringent BS VI emission norms control of Particulate Matter in diesel engine exhaust emission is currently achieved through DPF, catalytic convertors, baffle filters of various design. In the present research, a device comprises of a spiral duct with 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 device is fitted in the exhaust system of a diesel engine 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 PM & NOx . 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.
