In Malaysia, two-stroke motorcycles are favorable due to its higher performance and cheaper maintenance cost compared to four-stroke motorcycles. However, its disadvantages in terms of emission required improvement in existing exhaust system. This paper investigates the potential capability of using porous alumina-zeolite (PAZ)filter in reducing hydrocarbon HC)and carbon monoxide (CO) from a two-stroke 110cc carburetted motorcycle engine. The impact on engine performance was also investigated. The filter employed polymeric sponge method to produce porous structure with a composition of 70 vol. % alumina and 30 vol. % of zeolite, coated with stanum (IV) oxide. It was installed in the muffler of the original exhaust system and its performance was tested using Dynomite Chassis Dynamometer and emission analyzer. The testings were conducted from 2000 to 3000 rpm using three different configurations namely non-coated PAZ filter, coated PAZ filter and non-filter system.Results show lower exhaust gas emission which indicates the potential capability of using PAZ filter in the existing system without requiring major modifications on the system.
