Experimental study of vapor carburetor using bubbling and splash method on fuel consumption on motorcycle

Abstract

Liquid fuel type gasoline is a volatile fuel. The volatile of the fuel will make it easier for the fuel to mix with air and increase mixed homogeneity. Vapor Carburetor technology converts liquid fuel into steam for combustion. This study aims to determine the effect of the evaporation technique using the bubbling method and the splash method on fuel consumption. The bubbling method creates fuel vapor by making bubbles on the liquid fuel while the splash method creates turbulence in the liquid fuel to produce fuel vapor. This study uses an experimental method with a research object of a 4stroke gasoline engine with a capacity of 100cc. The fuel used is RON 90 type with the calculation of ml/minute fuel consumption, and data analysis using quantitative descriptive. The results of this study will compare the vapor carburetor with several evaporation methods using bubbling, splash, and combined. The results showed that the level of vapor carburetor fuel consumption was lower than conventional carburetors with the following percentages: 28.8% bubbling method, 39.1% splash method, and 28% combined method. This study shows a reduction in fuel consumption and can be implemented in the future to reduce fuel consumption.
