Abstract

As activities increase, people increasingly need safe, comfortable and adequate means of transportation to support mobility. As a result, over the times the amount of traffic and the type of vehicles using the streets is increasing. This causes problems in the transportation sector, one of which is the problem of back pressure, temperature and noise pollution (noise) caused by vehicle exhaust. Therefore, efforts to reduce noise and back pressure from vehicle mufflers need to be done. One of them by using a dual bed catalytic converter made of copper and brass. The dual bed catalytic converter functions as a reduction of emissions while reducing noise and improving engine performance. The purpose of this study was to determine how much improved engine performance by using a copper and brass dual bed catalytic converter on a Honda Vario Techno motorcycle. The research conducted was an experimental research (experimental research). Data analysis uses quantitative descriptive method. Based on the results of the study it can be concluded that the use of a dual bed catalytic converter made from copper and on a Vario Techno 125 CC motorcycle can increase torque, power and reduce noise levels. The highest increase in torque at 16.70% catalytic brass-copper was obtained at 4000 rpm and copper-brass catalytic at 10.06% obtained at 8000 rpm rotation. The highest increase in effective brass-copper catalytic power of 2.40% was found at 3000 rpm rotation, while the highest copper catalytic copper was 3.20%. Besides the dual bed catalitic made of copper and brass converter in the exhaust Honda Vario Techno 125 CC can reduce noise levels highest on Copper-Brass catalitic of 3.08% obtained at 4000 rpm rotation and a decrease in the highest noise levels at catalitic Brass-Copper at 5.6% at 4000 rpm.
