Optimization of Material Variations and Installation Angle Catalytic Converter in Muffler to Emission Gas

Listiyono .


Air pollution from burning fossil fuels (oil and coal) continues to rise. Many efforts have been made. Starting from the reduction of the combustion process to providing equipment as a reducer of exhaust emissions or increase the quality of combustion, but still high air pollution. Especially the combustion of gasoline engine. As the number of motors continues to increase significantly.Automobile air pollution comes from exhaust gases from unburned or burning combustion. The poor exhaust gas is caused by incomplete combustion of fuel in the combustion chamber. The elements contained in the flue gases include CO, NO2, HC, C, H2, CO2, H2O and N2, among these gases very radical are CO and CO2 gases. CO gas is a poisonous gas if humans inhale this gas can cause death. While CO2 gas is a radical that can cause an increase in geothermal greenhouse effect.The purpose of this research are: 1 Knowing the effect of converter catalyst material and installation angle to decrease CO and CO2 emission in motor vehicles. 2. Seek material type and installation angle a catalyst converter of optimum to reduce emission of CO and CO2 exhaust of motor vehicles.Research and development with the aim to reduce exhaust emissions until now has been done by installing the katalic on the exhaust. In this study studied are copper, brass and stainless steel. While the variation of installation angle is 60o, 90o and 120o. Especially the poisonous gas. The material is mounted on a muffler filter. Analysis using Minitab software and it can be concluded that: 1. Catalyst converter material and mounting angle effect on CO and CO2 gas emission can  reduction. 2. To produce toxic exhaust gas emission optimum is stainless steel material with installation of catalytic converter corner 600.
