Abstract:
With the increased motor cycle, every year have been affecting the populated from combustion gas, one of the technology that can reduce the amount of combustion gas is to install filters on the exhaust nozzle. Exhaust filters is a porous permeable ceramics filterer, where it should aid or hasten the filtering process like carbon monoxide (CO) and hydro carbon (HC). In this experiment using three types of combined fly ash and kaolin. From the result known that combined fly ash and kaolin can reduce emission gas of CO and HC as well as the noise level. In result known that exhaust filters is superior in overall performance and reducing HC emission than any standard exhaust nozzle. Comparing between nozzle without filterer, with type A composition the highest percentage of HC decreased emission by 87.89% in idle rpm, while the highest percentage of CO decreased emission by 78.21% in idle rpm. On type B composition, the highest percentage of HC decreased emission by 85.29% in idle rpm, while the highest percentage of CO decreased emission by 72.13% in idle rpm. Last with type C composition the highest percentage of HC decreased emission by 76.11% in idle rpm, while the highest percentage of CO decreased emission by 66.57% in idle rpm.
