Comparison of Three Way Catalytic Converter Exhaust Gas with Pertalite, Pertamax, and Pertamax Turbo Fuel in Gasoline Motor

Abstract

Transportation emissions are the highest contributor to air pollution, which is around 85%. One technology that can be used to reduce exhaust emissions from transportation is by installing a catalytic converter in the exhaust emission exhaust system. This study discusses the use of catalytic converters to reduce carbon monoxide (CO) and hydrocarbons (HC) with variations in engine speed and fuel. The catalyst used is a three-way catalytic converter model. The engine speed used is idle, 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm, 3000 rpm, 3500 rpm. The variations in the fuel used are pertalite, pertamax and pertamax turbo. The use of catalytic converters can reduce the concentration of CO and HC with all three types of fuel. The biggest reduction in CO and HC concentrations reached 39.5% and 22.7%. From this study, it can be seen that the use of catalytic converters can reduce exhaust emissions. The greater the octane number of the fuel, the less CO and HC emissions contained in the exhaust gas. The use of catalytic converters can be a solution to overcome the problem of pollution caused by transportation equipment because of its ability to convert hazardous compounds to exhaust emissions into harmless gases.
