Environmental Pollution Control Using Nano-Particles in SI Engines

The purpose of this paper is to present nanotechnology is covering various technologies which are in progress at nano-scale. It plays a essential role in the creation of new methods to produce new-fangled products, to replace existing production equipments and to develop new materials having a much better performance leading to lesser amount of consumption of energy and reduced ecological degradation. This research paper focuses on the utility of the nano-particles in the area of automobile pollution control. The change of particle size from micro to nano causes significant change in the material properties. These properties can be vital in the reduction of pollution from environment which has become a serious problem today. Use of Catalytic Converter was found the best way to control the automotive exhaust emission among all of technologies and the coating of nano-particles on the catalytic converter of automobiles will help in decreasing the level of exhaust emission concentration and thereby, reduce the pollution level in atmosphere. This review paper deals with the automotive exhaust emission and its effects, automotive exhaust emission control by use of catalysts used in catalytic converter, atomic activity of nano particles and also the various nano-particles used in the automobile pollution control.
