| Summary: | Porous ceramics have received wide recognition in industrial applications as a filter to
trap particulates, ions and gases. Nevertheless, considerable attention has been given to improve
its treatment capability in the exhaust emission control technology. This research focuses on the
application of porous ceramic/zeolite filter on the exhaust system of 1300 cc gasoline engine.
Emission analysis on four compositions of filters has been investigated and the comparison is
made to the standard ceramic catalytic converter available in the market. A filter with the
composition of 90 vol.% alumina, 10 vol.% zeolite with additional 50 vol.% yeast exhibits
significant results in reducing both hydrocarbon (HC) and carbon monoxide (CO). Other filters also work effectively towards HC treatment but the reduction of CO only obviously improves above 1800 rpm. Further experiments indicate the use of filter independently has outperformed
other configurations by presenting the lowest normalized emission for CO and HC. Therefore, porous ceramic/zeolite filter has shown its outstanding potential to improve the emission performance of gasoline engine. |
