Changing the Material of a Diesel Engine Catalytic Converter to Reduce Exhaust Emissions

EasyChair Preprint 4924

Abstract

In automobile industry, the exhaust from the internal combustion engine is a complex mixture of gases and fine particles. Many pollutants are introduced in the environment such as Carbon Monoxide (CO), Nitrogen Oxides (NOx), Hydrocarbons (HC), etc. These pollutants may lead to affect the respiratory system as well as increase the risk of heart problems, premature death and lung cancer. To control the emission of these pollutants in environment catalytic converters are used. The commonly used catalyst in converters is mostly a precious metal such as Palladium, Palladium and Rhodium. Platinum is widely used and very active catalyst, but is very expensive. Rhodium is used as reduction catalyst, while Palladium is used as oxidation catalyst. Since, these materials are expensive the cost of catalytic converter increases. Thus the purpose of the project is to improve effectiveness of catalytic converter by using a different material along with the regular used noble metals. These materials perform the same task along with the catalyst and the additional task of storing and releasing oxygen during rich mixture combustion.
