Due to the stringent emission norms, the reduction of emissions from the engines has become necessary. Diesel engines produce less carbon emissions when compared but it is necessary to reduce NOx emissions in the diesel engines. this project is focused on urea-SCR system as De-NOx system the urea in the form of Adblue solution is injected into the exhaust system by using a ?decomposer? separated from the exhaust tail pipe. Urea is injected into the decomposer in the form of Adblue (aqueous solution of 32.5% urea) which is also known as diesel exhaust fluid. Decomposer is where the Adblue solution decomposes into ammonia and CO2. Adblue solution is injected into the decomposer by using a pump and an injector. A blower is inserted into the decomposer for the atomization of the urea droplets. Urea reacts with the exhaust gases in the exhaust line to form nitrogen gas (N2) and CO2. The decomposer and the injector is designed in ?CATIA? the analysis of flow of exhaust gases are carried out in CFD. The experiment is conducted for different loads at different conditions and results are calculated.
