A Novel System Based on the Principle of Electrochemical Treatment to Reduce Exhaust Emission from Gasoline-Operated Engine

摘要

The rising population is closely related to the improvement and importance of transportation. Moreover, the rapid increasing Indian economy also entangles manufactures in enhancing the performance of internal combustion engine. The increasing number of vehicles with speedy advancement of technology is leading world to have around 2 billion vehicles by 2020. The exhaust emission from these vehicles is also contributing to myriad problems. The exhaust contains harmful gases like carbon monoxide (CO), hydrocarbon (HC), sulfur oxides (SO_x), nitrogen oxides (NO_x), and particulate matters PM2.5 and PM10. Keeping in mind the Environment Act, 1986 of India and The Air (prevention and control of pollution) Act, 1981 of India, this paper is prepared for the betterment of our environment, and related to this is an idea to introduce an exhaust system in addition to three-way catalytic convertor for reducing the gases such as sulfur dioxide (SO_2), carbon dioxide (CO_2), and particulate matter emitted from vehicles comprising a heat absorbing freezer gel pack chamber which would be immediately preceded by the catalytic converter. A chamber containing graphite electrodes in aqueous electrolyte water to absorb sulfur dioxide (SO_2) and a chamber for absorbing carbon dioxides (CO_2) in alkali solution and for trapping particulate emitted in exhaust by catalytic convertor filler layer is being used.
