Report on Design and Development of Catalytic Converter With Ammonia Injection to Reduce Exhaust Emissions

Abstract

The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to this there is steep increase in the number of four wheelers during the last two decades. All these are increasing exhaust pollution and particularly in metros as density of these vehicles in metros are very high. The main pollutants contributed by I.C. engines are CO, NOx unburned hydro-carbons (HC) and other particulate emissions. In addition to this, all fuel burning systems emit CO2 in large quantities and this is more concerned with the Green House Effect which is going to decide the health of earth. Lot of efforts are made to reduce the air pollution from diesel engines and regulations for emission limits are also imposed in a few cities of India. An extensive analysis of energy usage and pollution shows that alternative power systems are still a long way behind the conventional ones. Further developments in diesel engine exhaust system i.e. catalytic converter will make difference in exhaust emissions. Catalytic converter is an exhaust after treatment, emission control device. In present assessment Non-noble materials use as catalyst in catalytic converter and ammonia injection system to reduce exhaust emissions. All exhaust emission measure with the help of emission analysis instrument i.e. AVL DIGAS 444
