Experimental Study on Automobiles Exhaust Emission Control
Main Article Content
Abstract
The biggest question today before the metropolitan population of our country in particular is, “Pollution is, snuffing us out” and pollution ever be controlled? There are no doubts that the progress was achieved in the last few decades in some areas in very negligible in comparison with the overall picture. For the controlling of automobile exhaust emission, the honorable Supreme Court of India, in June 1999 ruled that vehicular emission had to be reduced at a much quicker pace than planned so far. Engine manufactures was facing the challenging task to quality find solutions that are production feasible, technological explained with Euro norms, and therefore, they have been changing the concept of IC engine design, multipoint fuel injection system, Catalytic Converter and incorporation of Exhaust Gas Recirculation (EGR) remarkably. To reduce the automobile exhaust emission the several control equipment’s are:
1. Catalytic Converter,
2. Exhaust Gas Re-circulation (EGR),
3. Air Aspiration System,
4. Positive Crankcase Ventilation, etc.
NOx control system that recycles a small part of the inert exhaust gas back through the manifold to lower the combustion temperature and this system is called Exhaust Gas Re-Circulation system. Catalytic converter converts harmful gases to harmless gases. A catalyst is a material that causes a chemical change without entering into the chemical reaction. For example, in the Catalytic converter converts harmful gases to harmless gases. A catalyst is a material that causes a chemical change without entering into the chemical reaction.
