As most of the transportation sector is dependent on spark ignition (SI) engines, it is important to develop clean and efficient gasoline and renewable fuel blends. However, the novel fuels often have detrimental impact on gasoline combustion in terms of emissions and knocking. In the CleanSI project, tri-component fuels involving gasoline and two other renewable fuels are studied for SI engine application. In such a blend, one renewable fuel suppresses the disadvantages of the other to provide clean and efficient SI engine operation. Chemical kinetic mechanisms for the tri-component fuels are developed. Sophisticated numerical and experimental tools are used in this project for assessing the influences of novel fuels on gasoline combustion. With CleanSI, totally new and radical findings are expected in the field of gasoline and novel renewable fuel blend combustion chemistry. The outputs of this project help the implementation of renewable fuels to gasoline engines more efficiently.
