Development of emission control systems for reducing the toxicity levels of exhaust emissions is one of the major challenges faced by automotive industry which rely on diesel engines owing to its thermal efficiency and service life. The major challenge faced for implementation of emission control system is the periodic regeneration of channels in diesel particulate filter to avoid clogging and backpressure rise inside the substrate. Commercial fuel based regeneration is leading to uncontrolled combustion inside the filter substrate affecting its service life. State of art of the emission control system has been detailed by conducting literature survey on the area and it has been found that these systems have a vital role in reducing emission levels to meet emission norms. Microwave based active regeneration has been proposed in this paper to improve the service life and effectiveness of diesel particulate filter. Three dimensional models of the axial flow, radial flow and cylindrical oxidation catalysis system are developed using Computer Aided Design software and flow analysis has been conducted using Computational Fluid Dynamics software (ANSYS FLUENT). Validation of the geometric design is done using simulation results and the pressure drop across the system is found to be in acceptable range.

Abstract


Development of emission control systems for reducing the toxicity levels of exhaust emissions is one of the major challenges faced by automotive industry which rely on diesel engines owing to its thermal efficiency and service life. The major challenge faced for implementation of emission control system is the periodic regeneration of channels in diesel particulate filter to avoid clogging and backpressure rise inside the substrate. Commercial fuel based regeneration is leading to uncontrolled combustion inside the filter substrate affecting its service life. State of art of the emission control system has been detailed by conducting literature survey on the area and it has been found that these systems have a vital role in reducing emission levels to meet emission norms. Microwave based active regeneration has been proposed in this paper to improve the service life and effectiveness of diesel particulate filter. Three dimensional models of the axial flow, radial flow and cylindrical oxidation catalysis system are developed using Computer Aided Design software and flow analysis has been conducted using Computational Fluid Dynamics software (ANSYS FLUENT). Validation of the geometric design is done using simulation results and the pressure drop across the system is found to be in acceptable range.
