Paper Title
Vehicular Emission Control Techniques

The catastrophe is nearing. If the two World war is between human being then the third one is between human being and the nature. The biggest Problem of the 21st century is the greenhouse effects which have their source in the vehicular emission. Vehicular emission contains primary greenhouse gases- carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and other pollutants- carbon monoxide (CO), total nitrogen oxides (NOX), sulfur dioxide (SO2), and particulate matter which all are responsible for a number of adverse environmental effect such as photochemical smog, death of rain forests, acid rain, health hazards and reduced atmospheric visibility. This paper reviews the new paradigm of emission control techniques. Keywords— Emission control, Catalyst, SCR, Fuel Injection, HCCI, Reformulation.
