Abstract

Nowadays, after treatment, technology has been widely applied by oxidizing harmful exhaust emissions into more environmentally friendly gases. However, the technology for oxidizing these emissions uses relatively expensive platinum and rhodium catalysts. This study offers a simple exhaust gas oxidation technology by utilizing heat energy and a very cheap steel sponge material. The method used in this study is to utilize exhaust gas energy to the oxidation chamber of a steel sponge through an exhaust manifold with a heat-insulating layer. The steel sponge oxidation chamber is also lined with heat insulation for the steel sponge^s optimal heat absorption. Fresh air is entered through the non-return valve due to the difference in environmental pressure with low pressure due to exhaust gas flow velocity. The results of this study indicate that the addition of fresh air is effectively applied to reduce carbon monoxide emissions, but does not significantly reduce hydrocarbon emissions. Carbon monoxide is polar, so it is very easily oxidized with the addition of fresh air so that this system is effectively applied
