The toxic nature of the exhaust gases emitted from diesel engines has led to the development of emission control systems like diesel oxidation catalysis, diesel particulate filtration and selective catalytic reduction. The particulate matter emitted by these engines is found to be carcinogenic in nature. Diesel particulate filter (DPF) is used for trapping the particulate matter which consists of soluble organic fraction and soot particles. The regeneration of these accumulated soot particles is one of the major problems faced in these systems. Active regeneration takes place in the traditional DPF by injecting the fuel to the filter and then initiating combustion by introducing spark. It will lead to uncontrolled combustion causing serious damage to the filter. Electromagnetic waves in microwave region can be used for regeneration of the accumulated soot. Detailed literature survey has been carried out on the application of microwave energy for the regeneration purpose, and an emission control system has been proposed in this paper.
