The effect of bubbling method in vapor carburetor using fuel variations on fuel consumption on motorcycle

The increase in the number of motorized vehicles in Indonesia increases the amount of consumption of fossil fuels so that the fuel supply is running low. Technology that is developing at this time has not been able to produce an optimal role in saving fuel consumption. The need for new technology to keep the consumption of fossil fuels. This study aims to determine the effect of vapor carburetor using the bubbling method to reduce the level of fuel consumption. The Vapor carburetor evaporates fuel by making air bubble trough fuel. This study uses an experimental approach with a research object of a 100cc single-cylinder gasoline engine. The fuel used is RON 90, RON 92, RON 98 through the calculation of fuel consumption of ml / minute. Data analysis using descriptive quantitative. The result of the study shows that increases in fuel-saving value of 28.26% RON 90, 29.68% RON 92, 24.6% RON 98. This result indicated that there is an effect of using a vapor carburetor with bubbling method in saving fuel consumption can be using used in the future fuel system.
