Energy Recovery from a Yamaha Mio Aerox 155 Motorcycle Using Turbine-Driven DC Generator with an Integrated Electrostatic Coarse Particulate Filter

Abstract—The worsening traffic conditions in the Philippines have increased the demand for motorcycles. This becomes a reason for more air pollution. One component of air pollution is particulate matter. Motorcycles emit more PM than passenger vehicles per vehicle-mile traveled [2]. PM kills more than fivehundred-thousand people annually through cardiac and respiratory damage [1]. In addition to air pollution, there is also wasted wind energy coming from motorcycle exhaust. Both the pollutant and the wasted energy are found in the exhaust wind emissions. The problem was addressed through an energy harvesting device with an integrated electrostatic coarse particulate filter. The harvesting device was comprised of a turbine, a generator, and an exterior. These components were fabricated using aluminum. On the other hand, the filter was made of aluminum plates and a 3D-printed exterior. With these two components attached to the motorcycle’s exhaust, the wind energy was converted into electrical power, and the coarse particulate matter levels were decreased from the emissions. The generator reached max power generated at 5500 rpm, sitting at 858.97 mW. The linear regression analysis gave an R-value of approximately 0.94 which shows that there is a strong relationship between the rpm of the engine and the power generated by the generator. Meanwhile, in order to analyze the difference between the concentration of PM10 before and after the application of the electrostatic coarse particulate filter, the researchers used a t-test on the data. The two-tailed test resulted in a p-value<0.001 for Case 0 which shows that there is a statistically significant difference between the concentrations of the PM10 before and after the application of the filter. Moreover, Cases 1, 2, and 3 also had a p-value<0.001, which implies the same conclusion. A formula was used to calculate the efficiency of the filter. The average of all the peak efficiencies of the cases sits at 74.25%. These findings show that the prototype is feasible against air pollution and energy harvesting. Hence, the expansion of the research is imperative.
