Abstract -In this study, were the diesel engines produces lot of harmful pollutants to the atmosphere, the emission control method is used to prevent and reduce the emission of harmful gases. In order efficiently reduce the polluting emissions of engines by exhaust after treatment systems, We tried to control the reduction of emission implementation of post combustion techniques like Diesel particulate filter (DPF), Diesel oxidation catalyst (DOC), Selective catalytic reduction (SCR) are adopted for existing diesel engine to reduce the emissions and induce significant gain in emission reduction were tried. The paper summarizes developments in diesel emissions regarding regulations, engines, Particulate matter (PM) reduction, and hydrocarbon (HC), and CO oxidation.

Keywords- DOC, DPF, SCR, Diesel engine, New Catalytic converter.
