The discharge of harmful impurities put into air which creates unwanted effects to the environments and people. Inadequate engine combustion is one of the causes for air pollution with the emission of CO, HC, NOx, SOx soon. Whenever there is an incomplete combustion takes place huge volume of CO gas is released. If the fuel includes a high Sulphur concentration, the Sulphur in the petroleum combines with the oxygen during the combustion process and releases SO2. The unburnt hydrocarbon is due to incomplete combustion and NOx (Oxides of Nitrogen) are leads to the formation of uninflamed gas in the exhaust with nitrogen. Hence, rigid norms of effluence emissions are enforced as safety measures which has made exhaust gas after-treatment systems important. In order to reduce the engineemission, the current method is the use of catalytic converter. This paper discusses an effective system for improving presentation of the catalytic converter by using an embedded controller in proportion with emission.
