Development of a 4-stroke motorcycle fuel system to support E85 gasohol and comparison with the fuel consumption rate of gasohol 95, 91 and E20

Abstract

The objective of this research was to develop a 4-stroke motorcycle fuel system to support E85 fuel in order to identify the consumption rate of E85 gasohol, to compare the consumption rate with gasohol 95, 91 and E20 and to measure the amount of exhaust gas analysis by installing the processing box into a 4-stroke motorcycle, Honda Wave 110i and adjusting the mode to use E85 fuel. It was found that the engine starts smoothly without any problem. As for the fuel consumption rate of gasohol 95, 91, E20, E85 at the 60, 70, 80, 90 kilometers per hour (km/h) speeds test and at the distances of 10, 20, 30 kilometers (km), it was found that the lowest to highest values were Gasohol 95, 91, E20, and E85, respectively. However, when using higher speeds and longer distances, the values started to be similar for all fuel types. The E85 fuel exhaust gas content was 0.29% by volume. The HC value was 50.5 ppm. In conclusion, when the E85 processing box was installed, the motorcycle operated smoothly without any problem. As for the fuel consumption rate, Gasohol 95 and 91 had lower values than E20 and E85 because E20 and E85 contained a higher amount of ethanol. This resulted the need to use more fuel for the same distance test. However, E85 was cheaper and when using higher speeds and longer distances, the fuel consumption rates started to be similar. The emission levels from the analysis were within the standard.
