Experimental Investigation of Three-Way Catalytic Convertor Based on Cerium and Titanium in C.I Engine

This project presents the characteristics of a new catalytic converter to be used for diesel fuelled engine. Two types of catalytic converters were developed to reduce emission effectively with low cost which is based upon the catalyst material. The metal oxide such as titanium dioxide (TiO2), cerium oxide (CeO2), copper nitrate (Cu (NO3) 2), and Zirconium dioxide (ZiO2) with wire mesh substrate were used. Both the catalyst material used in these catalytic convertors are inexpensive in comparison with conventional catalyst made up of nobal metals such as Platinum (Pt), Palladium (Pd) and Rhodium (Rh) which are currently in use. The nobal metals are identified as human health risk due to their rapid emissions in the environment. The Original Equipment Manufacture Catalytic Converter was tested for comparison purposes. The OEM catalytic converter was based on noble metal catalyst with honey comb ceramic substrate. The objective of this project is to develop a cost effective three way catalytic converter to be used in diesel fuelled engine. Detailed review on cost effectiveness, reduction of emission of new catalytic converter in diesel fuelled engine and test results have been reported with discussions.
