Prediction of WLTC Mode Drive Fuel Consumption of Vehicles Using Blended Gasoline

For the survival of internal combustion engines, the required research right now is for alternative fuels, including drop-ins. Certain types of alternative fuels have been estimated to confirm the superiority in thermal efficiency. In this study, using a single-cylinder engine, olefin and oxygenated fuels were evaluated as a drop-in fuel considering the fuel characteristic parameters. Furthermore, the effect of various additive fuels on combustion speed was expressed using universal characteristics parameters. In addition, the prediction of CO2 emission from passenger cars were carried out by changing the fuels. The CO2 emission in running WLTC was estimated using Modelica. As a result, it was found that the CO2 emission can be reduced by adding olefin and oxygenated fuels.
