Abstract: In addition to gasoline and diesel fuel, the biofuels HVO and FAME have been taken into wide use during the last decades.The properties of gasoline and diesel fuel and their effect on the combustion process have been studied for a long time, butstudies on HVO and FAME are still are very much work-in-progress. Existing studies show that the use of biodiesels reducesthe level of several exhaust gas emissions (like soot) in engine exhaust gases. At the same time, the reasons for the reductionof emission compounds remain unclear. The motivation behind determining drop size and behavior is to aid assessment ofthe quality of the air-fuel mixture with a view to explaining the reduction in soot emission when biodiesels are used. The aimof this review paper is to provide an overview of the behavior of fuel drops and their size in fuel injectors when using differentbiofuels by giving a theoretical background based on literature, on the basis of which the calculations give an opportunity toevaluate experimental results of the behavior of different biofuels in the fuel spray. This study compares four different fueltypes according to the WAVE-RT model. In addition, the collision mechanisms of drops (reflexive and stretching separation)are presented and these shall be compared for the fuel types. The results show that during the use of biofuels, the drop sizeis somewhat larger compared to diesel fuel.
