Abstract
This project aims the effect of ceramics material coating on a new designed catalytic converter is used in diesel fuelled engine with 10% of ethanol blend in addition of 1% of (DEE) Diethyl Ether as fuel additive. The catalytic converter was developed based on catalyst materials consisting of metal oxides such as titanium dioxide (TiO2) and Aluminum oxide (Al2O3) with ceramic substrate. Both of the catalyst materials (TiO2 and Al2O3) are inexpensive in comparison with conventional catalysts (noble metals) such as palladium, platinum and rhodium. In addition, the noble metals are now identified as human health risk due to its rapid emissions in the environment. The OEM (Original Engine Manufacturer) catalytic converter was based on noble metal catalyst with honey comb ceramic substrate. The designed and fabricated ceramic substrate coated with oxides of metals is TiO2 and Al2O3. In this study, experimentally found that the TiO2/Al2O3 based catalytic converter are reduce 12%, 23.46%, 19%, 35% and 77.9% for NOx, CO, HC, CO2 and smoke emissions respectively for diesel fuel . It is calculated that the TiO2/Al2O3 based catalytic converter with ethanol 10% in addition of DEE 1% reduces 15%, 52.8%, 39%, 40% and 81.7% higher NOx, CO, HC, CO2 and smoke emissions in comparison to diesel and ethanol. The objective of this paper is to develop a low-cost three way catalytic converter to be used with the newly developed ceramic catalytic converter and emission test results have been presented with discussions.
