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
