Diesel engines used in automobiles and other industrial applications are found to be responsible for the emission of particulate matter and other toxic gases. The particulate matter is also carcinogenic in nature posing a serious threat to human life. Recent researches have shown that combined application of Diesel Oxidation Catalyst (DOC) filter, Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) can reduce these emissions to a certain extent. In this paper, a detailed literature survey has been carried out in this area and it was found that the development of an effective regeneration procedure is one of the major challenges in the emission control using these devices. Composite regeneration technique using electromagnetic waves in the microwave region and fuel additives have been proposed in this paper. As an initial phase of the project, the analysis of the design aspects of the DOC filter has been carried out. Uniformity of catalyst coating in the monolith substrate is determined using metallurgical microscope. Models with different lofts have been designed in SOLIDWORK 2014 x 64 and its flow analysis is carried out in ANSYS FLUENT 16.2. The results of simulation showed that model with loft angle of 62 degree has the lowest pressure drop. Fabrication of system has been carried out based on simulation results.Keywords
