The effect of swirl blades copper plate shaped catalytic converter for effectiveness in reducing motor vehicle exhaust emissions.

The increase in the number of motorized vehicles as a common transportation has an impact on increasing air pollution. Air pollution from motorized vehicles that exceeds the threshold will result in health problems and even death in certain cases. This is because motor vehicle exhaust emissions contain harmful pollutants including carbon monoxide (CO) and hydrocarbon (HC). One of the technologies that can be used to reduce motor vehicle exhaust emissions is a catalytic converter which is installed in the exhaust duct of motorized vehicles. Catalytic converter is a tool to HC and CO emissions by using oxidation and reduction catalysts. One alternative material that can be used as a catalyst is copper (Cu). The purpose of this study was to determine the effect of using a catalytic converter with a copper (Cu) catalyst on the concentration of carbon monoxide (CO) and hydro carbon (HC) gases in the exhaust gas of a 150cc 4 stroke motorcycle. The method used is experimental, namely designing and designing a copper catalytic converter with a perforated spiral shape. Furthermore, testing and comparison of exhaust gas emission results without and using Catalytic is carried out. Based on the research results, the copper catalytic converter in the form of Swirl Blades can reduce HC gas by 41 ppm, CO by 28% and CO2 by 32%. [ABSTRACT FROM AUTHOR]
