Abstract
The demand for fuel is increasing along with the growth of the motor vehicle population, especially motorcycles. Currently, motorcycles rely on oil-based fuels, producing unhealthy exhaust emissions. One way to reduce fuel consumption and the resulting exhaust emissions is through the implementation of an electrolyzer. The electrolyzer is capable of saving fuel consumption and improving the engine combustion system. The objective of this research is to analyze the influence of adding an electrolyzer to the motorcycle fuel system on fuel consumption and exhaust gas. This study was conducted on a carbureted motorcycle that has been modified with injection. The results of fuel consumption and exhaust gas emission tests with electrolyzer treatment were compared with those without electrolyzer treatment. The results showed a decrease in fuel consumption at 2000 RPM by 31.36%, at 4000 RPM by 8.73%, and at 6000 RPM by 15.48%. In terms of exhaust gas emissions, CO decreased by 47.37%, CO2 increased by 24.37%, and HC decreased by 45.11% at 2000 RPM. At 4000 RPM, CO decreased by 89.11%, CO2 increased by 35.48%, and HC decreased by 36.98%. And at 6000 RPM, CO decreased by 41.67%, CO2 increased by 17.26%, and HC decreased by 6.92%.
